Definitions
- the invention is related to optics and, more accurately, the extender of the optical beam is affected.
- the extender of the optical beam is known, which is expanding in the plan of the optical waveguide, which contains the waveguide lens (see. ⁇ ⁇ Brass ⁇ Corporation1: ssen ⁇ ⁇ grade ⁇ ⁇ Maschinenshell ⁇ ⁇ Maschinenshell ⁇ ⁇ Maschinenshell ⁇ ⁇ réelle ⁇ ⁇ т ⁇ ⁇ о ⁇ о ⁇ engine ⁇ engine, 1 ⁇ level ⁇ _ ⁇ just ⁇ rion flesh Canal ⁇ beaut_ ⁇ 1 ⁇ êt, 1990, ⁇ . 8, 12 ⁇ 12, ⁇ . 1833-1837).
- the device works similarly to the standard light beam, created on a bulk lens.

- the extender of the beam is also known ( ⁇ . , 4 ⁇ 4, ⁇ .165-166), in addition to the expansion of the beam in the waveguide is carried out with the help of the Braggs diffuse.
- ⁇ 0 is the wavelength of light in a vacuum
- ⁇ is an effective indicator of the distribution of directional water pressure.
- the device ensures a 90-degree shutdown of a narrow (less than 1 mm) light beam falling on a diffused baffle.
- the width of the extended beam can be 5–10 mm. It depends on the parameters of the interacting wavelengths and diffraction gratings.
- ⁇ Due to the faulty device, the glass circuit was removed from the device due to the malfunction of the blackout; The lattice had a transition of 0.6 ⁇ m and a depth of 0.3 nm.
- the basic invention has the task of creating an expander bundle, which would have a minimal size and low emissivity.

- the angle of inclination of the elementary gears of the consumer is free and equals to 45%.
- this “a” area should be small enough to facilitate tunneling through an unfavorable mass of water.
- the cumulative discharge is the “a” value of the dividing area, which is equal to the order of magnitude, the widest part of the world, step 5-20 microns. ⁇ case, when the polar optical waveguide 3 was carried out not immediately in Planning an optical wave 2 (see Fig. 2), tear off the light bulbs in the case of a short circuit and disconnect from another
- the angular protector of the extender is provided with a beam with 0.7 cm aperture for two typical cases.

- the operation of the device is carried out by the following method.
- the narrow optical beam is introduced into the user-supplied optical wave 3 and after input 5, and thus, each of the elementary 4 carriers is divided into two.

- the following is a general guide to the offer of the extender, the handle of the extender, and the beam with a large diffractor.
- the last light In the case of the last light, it falls on the dividing diffuse lattice in the case of bragging angle and is blocked in the diffraction order. This is due to the possibility of having a diffuse circuit with a very small overload (only slightly), which is due to the inconvenience of ⁇
- the device, according to the invention does not use the effect of the Bragg distribution, but rather the interference of the light of interest, of which there are many factors.
- the idea is ideal in the highest order of interference, i.e. The difference in phase between the adjacent beams is much larger (about 10 times), which exceeds 2 ⁇ .
- ⁇ is the sine of the angle of observation, which is measured by the negative axis, which corresponds to the beam direction, the radiated by an elementary carrier.
