TRANSMITTER-RECEIVER OPTICAL DEVICE Russian patent published in 2023 - IPC G01S17/02 G01C3/08 

FIELD: optical-electronic instrument making.

SUBSTANCE: invention relates to optical-electronic devices for range measurement and can be used in the development of multi-channel optical systems. The transmitting-receiving optical device contains a radiation source, rotating mirrors, a radome, a telescopic system, an attenuator, a receiving lens and a photoreceiving device. The attenuator is made of two parallel prisms that rotate the radiation flow passing through them by 90°, and two electro-optical elements parallel to each other, to which voltage is applied at the moment of radiation. Each prism consists of two wrapping prisms glued together and contains a polarizing coating applied to the bonding surface, with the optical axes of the prisms perpendicular to the optical axes of the electro-optical elements.

EFFECT: invention provides an increase in the maximum measurable range.
