Abstract
Provided is an optical system, comprising an infrared source used to provide infrared beams, a microwave source used to provide microwave beams, and a beam synthesizer with a round hole. The beam synthesizer is used to reflect the microwave beams and the infrared beams entering from the round hole go through the beam synthesizer. The diameter D of the round hole is D=d+2 (L-l)tg[omega]+2[sigma], wherein d is an exit pupil diameter of the infrared source, L is an exit pupil distance of the infrared source, 2[sigma] is optical field angle of the infrared source, l is a distance from the beam synthesizer to the last surface of the infrared source, and [sigma] is radial installation error between the infrared source and the beam synthesizer. Light-through aperture value of the infrared light-through hole on the beam synthesizer is reasonable, the value is not too large which may increase processing difficulty of the beam synthesizer, and the value would not be too low to influence transmitance of the infrared light.
Description
Technical field
The utility model relates to a kind of optical system, and this optical system comprises infrared light supply, microwave source and beam synthesizer.
Background technology
The advantage that multimode combined guidance can be given full play to each self mode makes up the other side's inferior position, thereby improves the fighting efficiency of weapon.Microwave and infrared sensor composition infrared/microwave target seeker, can improve antijamming capability and the reliability of guided missile.Utilize the far away and high feature of infrared sensor measuring accuracy of the operating distance of microwave, identification and the tracking power of raising guided missile to target.
In infrared/microwave combined guidance emulation technology, the infrared and compound beam synthesizer of microwave is gordian technique wherein, and the large young pathbreaker of the infrared beam clear aperture on beam synthesizer directly affects its difficulty of processing, volume and weight.Definite Main Basis experience of the infrared beam clear aperture in beam synthesizer of the prior art, clear aperture is bigger than normal will increase the difficulty of processing of beam synthesizer, and clear aperture is less than normal will affect the transmitance of incident infrared light.
Utility model content
The problem that the utility model exists for above-mentioned prior art makes improvements, be that the technical problems to be solved in the utility model is to provide a kind of beam synthesizer, infrared beam clear aperture on this beam synthesizer neither can be bigger than normal and increase difficulty of processing, also can be not less than normal and affect the transmitance of infrared light.
For solving the problems of the technologies described above, the utility model adopts following technical proposals.
A kind of optical system, comprise infrared light supply for infrared beam is provided, for the microwave source of microwave beam being provided and thering is the beam synthesizer of an infrared light hole, described beam synthesizer is for microwave reflection wave beam with by the infrared beam of infrared light hole incident, and the diameter D of described infrared light hole is:
D＝d+2×(L-l)×tgω+2δ
The exit pupil diameter that wherein d is infrared light supply, L is the distance of exit pupil of infrared light supply, 2 ω are the optics field angle of infrared light supply, and l is beam synthesizer last surperficial distance apart from infrared light supply, and δ is the radially alignment error between infrared light supply and beam synthesizer.
Further, described beam synthesizer is an off axis paraboloidal mirror.

The beneficial effects of the utility model are, the clear aperture value of the infrared light hole on the utility model beam synthesizer is reasonable, neither can be bigger than normal and increase the difficulty of processing of beam synthesizer, and can be not less than normal and affect the transmitance of infrared light yet.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, as shown in Figure 1, A-A is last surface of infrared light supply, and B-B is off axis paraboloidal mirror, and the distance of exit pupil of infrared light supply is that L, exit pupil diameter are that d, optics field angle are 2 ω.Between infrared light supply and off axis paraboloidal mirror, be to install mechanically fixingly, because both are partial installations, conventionally have radially alignment error δ.Off axis paraboloidal mirror is l apart from last surperficial distance of infrared light supply.Infrared light hole is positioned at the optical axis intersection place of off axis paraboloidal mirror B-B and infrared light supply, and the diameter D of this light hole is clear aperture.Off axis paraboloidal mirror B-B can reflect away being parallel to infrared light supply optical axis from the microwave beam of focus 1 position incident.
The optical property parameter of known infrared light source comprises: optics field angle 2 ω=1 ° 30 ', exit pupil diameter d=50mm, distance of exit pupil L=500mm, off axis paraboloidal mirror is l=100mm apart from last surperficial distance of infrared light supply, in the time of radially alignment error δ=5mm between infrared light supply and beam synthesizer, calculate clear aperture D=70.5mm according to formula D=d+2 × (L-l) × tg ω+2 δ.
In the time that the clear aperture of off axis paraboloidal mirror is 70.5mm, this clear aperture value is reasonably, neither can be bigger than normal and increase the difficulty of processing of off axis paraboloidal mirror, and can be not less than normal and affect the transmitance of infrared light yet.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing those skilled in the art, can also make without departing from the concept of the premise utility various variations.
