where β - the refraction angle of an extraordinary ray; f - the focal length of the transmitting optical system; ϕ0 - the maximum permissible angular divergence of the output radiation in the plane of the minimum dimension of the radiating area; no - the refractive index of the ordinary beam of a bi-refringent plane-parallel plate; ne - the refractive index of an extraordinary ray; Do - the diameter of the transmitting lens.;EFFECT: most efficient use of the total energy of the probing radiation for long distances and the ability to measure shorter distances with rough guidance, for example, when working with hands.;2 cl, 5 dwg"/>
