As shown in Figure 1, the dizzy device main frame of hand-held laser-induced is made up of hot spot adjuster, laser instrument cabin (interior dress all solid state laser and circuit thereof), battery flat, safeties and power button (Fig. 1 is an Organization Chart, Gu not shown power button).Wherein the hot spot adjuster is rotatable, and closely links to each other with the laser instrument cabin, and marine glue is smeared in the junction; The laser instrument cabin cooperates with battery flat, and the surface is structure twist, helps heat radiation; Safeties are positioned at bottom, the dizzy device of laser-induced rear end, adopt waterproof construction, and install sealing gasket additional; Power button is positioned at the dizzy device housing of laser-induced middle part, under discharge cock is in open mode, presses power switch, will launch laser.Auxiliary equipment has rechargeable battery, charger, portable bag and packing case No. 2; The apolegamy part has goggles, leather sheath etc.

In the hot spot adjuster lens combination is housed, can continuously changes the size of irradiation hot spot, to be fit to different application requirements.Safeties design for fear of maloperation, when being allocated to closed condition, even have under the situation of battery, press power switch also can not connect; Place No. 2 batteries of two joints in the battery flat, be the laser instrument power supply; Lay all solid state micro-slice laser and circuit unit thereof in the laser instrument cabin, under safeties are in open mode, press power key, will launch laser.The housing of laser instrument cabin and battery flat is selected the aluminum alloy materials of perfect heat-dissipating for use, the heat radiation when being convenient to laser works.In order to cooperate the use of army under different weather and environment, the structural design of the dizzy device of laser-induced should realize waterproof, rainproof, uses to be applicable under different weather and environmental condition.Concrete solution one is to guarantee good air-tightness on the material selection of housing and structural design, and the junction design of each parts is tight, and smears marine glue; The 2nd, reduce the assembly on the housing as far as possible, guarantee the globality and the air-tightness of housing; The 3rd, adopt water proof switch, guarantee not have in the button process steam and infiltrate.

Following elder generation describes the hot spot Principles of Regulation of using in the utility model.According to mission requirements, should be able to change between the 1500mm at 150mm at hot spot from exit portal 50m place.

If angle of divergence θ in the laser parameters ₀Be 10mrad, then be about at 50m place spot diameter:

${\mathrm{\Φ}}_0\≈S\·{\mathrm{\θ}}_0=50000\×\frac{10}{1000}=500\mathrm{mm}$

By calculating as can be known, surpassed the requirement of 150mm, put optical system and make it to reduce so should add.The beam expanding lens system of an adjustable focal length has been installed behind negative lens 2 for this reason, and its optical schematic diagram is seen Fig. 2.

As shown in Figure 2, laser tube 1 sends a branch of thin bright light beam, and the angle of divergence is less, is about 10mrad, after pancratic set of lenses of forming through negative lens 2 and balsaming lens 3, is variable from the divergence of beam angle of set of lenses outgoing.Select the suitable focal length of lens and lens at interval, it is adjustable continuously within the specific limits to can be implemented on the certain distance hot spot, and promptly being implemented in from the set of lenses distance is that the spot diameter at 50 meters can change between the 1.5m at 0.15m.It is in order to reduce spherical aberration and coma, to make the hot spot brightness ratio more even that balsaming lens 3 adopts gummed.

D among Fig. 2 is adjustable, suitably adjusts optical interval d between positive negative lens, makes it to become an inverted Galileo telescope, then according to the laser beam transformation theory, certain angle of divergence θ is arranged ₀Laser send from laser tube after, behind this inverted Galileo telescope, the angle of divergence of outgoing beam will reduce 5 times at least.

Then: ${\mathrm{\θ}}^{\′}=\frac{{\mathrm{\θ}}_0}{\mathrm{\Γ}}=\frac{10\mathrm{mrad}}{7}=1.43\mathrm{mrad}$

This moment, spot size was about Ф ₁=S θ '=50000 * 1.43 ≈ 72mm are less than the requirement of 200mm.When d reduced on this basis, positive negative lens group became a negative lens system, and the outgoing beam angle of divergence will be increased, and drew following result as calculated and through verification experimental verification:

During d=51.5mm, the spot diameter Φ=150mm of 50m place;

During d=48.0mm, the spot diameter Φ=500mm of 50m place;

During d=41.8mm, the spot diameter Φ=1000mm of 50m place;

During d=29.3mm, the spot diameter Φ=1500mm of 50m place;

That is to say, when optical interval between positive negative lens when 51.5mm changes in the 29.3mm scope, 50m place irradiates light spot diameter can change in the 1500mm scope at 150mm.

When according to designing requirement, optical system will realize the continuous adjusting of hot spot, mobile lens group 7 is at focusing pipe 6, doubly manage between 5 the helicla flute with change, do circumference and axially-movable by the guide screw 8 that is fixed on the mobile lens group 7 along the straight trough restriction on the helicla flute and the pipe 6 of focusing, realize changing the optical interval between fixed lens group 4 and the mobile lens group 7, the purpose of adjustment spot size.In order to represent that spot diameter is 150mm, 500mm, 1000mm, 1500mm fourth gear position, end face at focusing pipe 6 has four " V " shape grooves by the pairing corner of displacement, rotate focusing pipe 6, when groove is aimed at the steel ball hole, steel ball 9 snaps in " V " shape groove under the effect of its rear spring, and send clickly sound, provide the signal that focusing puts in place.In order to reach the effect of rainproof mildew-resistant, the sealing of " O " shape sealing ring has been adopted at focusing pipe 6 two ends simultaneously.The general structure design of system as shown in Figure 3.

Below in conjunction with Fig. 4 power control circuit is described.As shown in Figure 4, power circuit is core with U1, and additional peripheral circuitry C3, R2, C4 constitute multivibrator, and output provides reference voltage after R4, the voltage stabilizing of V1 amplitude limit.Reference voltage can be adjusted to appropriate level by R5, RP1 and give difference amplifier U3.Another input of difference amplifier is obtained by R7 sampling, and U3 output is by R6 control triode V3 conducting state, thereby obtains predetermined output after the colelctor electrode of triode is through adjustment such as C6, R9, V2.Power supply is added to circuit after C1, C2 filtering, and gives indication by R1, light emitting diode D1.Whole power circuit realizes that the 3V voltage transitions by input is the required 2.2V voltage of laser works.

For the dizzy device of laser-induced can both be used under different weather and environment, the utility model has been considered waterproof, rainproof requirement on structural design.Concrete solution is as follows: the one, the material of housing select and structural design on guarantee good air-tightness, the junction design of each parts is tight, and smears marine glue; The 2nd, reduce the assembly on the housing as far as possible, guarantee the globality and the air-tightness of housing; The 3rd, adopt water proof switch, guarantee not have in the button process steam and infiltrate.

The utility model in use should be noted that, the size of hot spot directly influences and is determining the threaten degree of armament systems, can change spot size by the hot spot adjuster, and the size of hot spot can (in distance be that the diameter of 5 meters hot spots is when being 0.15 meter along with the distance generation linear change of distance, diameter at 25 meters hot spots is 0.75 meter, is 1.5 meters at 50 meters hot spots).Therefore for the sake of security, should be controlled at the diameter of hot spot 0.30～0.75 meter night, and should be controlled at spot diameter 0.10～0.15 meter daytime.

In addition, the hand-held dizzy device of laser-induced is a kind of active attack armament systems, and laser can cause the permanent or temporary blind of human eye.Therefore, as one light, mechanical, electrical be the high-tech product of one, its every performance indications are required very strict, fail-safe analysis is one of them aspect.The requirement that the tactical and technical norms reliability need reach is: MTBF 〉=1000h.

The hand-held dizzy device belief system of laser-induced is divided into two parts: the one, and laser light source part comprises laser head and power circuit; The 2nd, the frame for movement part of optical system and battery flat.Because of system is the tandem type model, any one unit is out of order, and will influence the operate as normal of complete machine.Consider the distribution method of importance degree, its MTBF mathematic(al) representation is:

${\mathrm{MTBF}}_i=\frac{{\mathrm{NW}}_i{t}_i}{N_i{L}_{n}R}$

In the formula: N is total components and parts number; W _iIt is the weighted factor of I circuit board; t _iIt is the working time of I circuit board; N _iIt is the components and parts number of I circuit board; R is a system dependability.Reliability R is determined by following formula:

$R=e^{-\mathrm{\λt}}=e^{-\frac{t}{\mathrm{MTBF}}}$

In the formula: the t single working time.

If test single working time t is 8 hours, MTBF is 1200 hours, and substitution gets:

$R=e^{-\frac{t}{\mathrm{MTBF}}}=e^{-\frac{8}{1200}}=0.993$

The reliability that is circuit system requires 0.993.

Usually take all factors into consideration the complexity and the significance level of each circuit board, also need to each circuit board weighting.Hold the dizzy device of laser-induced at hand, owing to all electrical parts all are integrated on the power supply circuit board, so weighted factor gives 1.As shown in table 1.

Components and parts number, working time and the weighted factor of table 1 circuit

Element circuit	The components and parts number	Working time (h)	Weighted factor
				Power circuit	21	8	1

With the data and the reliability substitution formula of table 1, can draw the MTBF value of power circuit.
