Abstract:

Subject of study. Variants of circuit solutions of optical systems, distinguished by high aperture ratio at relatively low resolution, are proposed. Aim of study. Increasing the energy of the optical signal entering the optical information systems. Method. The proposed technical solutions are based on circuit solutions of a light guide optical systems of augmented reality with hologram mirrors used in the reverse beams path. Main results. The possibility of using the light guide with a hologram mirror as an aperture compressor in optical systems, for example, receiving optical communication systems in free space or laser rangefinders, is shown. Variants of schemes of optical systems with a light-guide aperture compressor operating in monochromatic radiation at several wavelengths and achromatic systems are presented. In the latest version of the optical system, it is proposed to use a diffraction grating with an asymmetric profile stroke instead of the hologram mirror. Practical significance. The proposed variants of circuit solutions allow to significantly increase the intensity of the optical signal received by them due to the use of a non-tunable aperture compressor built on the basis of the light guide with the hologram mirror.
