TELESCOPIC OPTICAL ANTENNA WITH PARALLEL RECEPTION AND TRANSMISSION CHANNELS SEPARATION Russian patent published in 2024 - IPC G02B23/04 H04B10/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to optical antennae of transceivers of laser communication terminals in open space between aircraft (airplanes, satellites, airships). Essence: device 1 includes a second optical hinge formed by plane-parallel mirrors 1.3.5, 1.3.6, conjugated with axial plane-parallel mirrors of the first optical hinge, and prism 1.6 BR-180°, conjugated with a plane-parallel mirror of a first optical hinge mounted on a second axis of rotation of rotary support 1.4, wherein between the pair of diagonal plane-parallel mirrors of the second optical hinge there is an additional negative optical component 1.5, the optical power of which is equal to the optical power of secondary mirror 1.2.

EFFECT: providing separation of transmitted and received streams of coherent signals with a common telescopic optical antenna; simplified design of optoelectronic systems using telescopic optical antennae, due to exclusion of optical units for separation of receiving and transmitting channels outside telescopic optical antennae; higher reliability.
