OPTIC TRANSCEIVING DEVICE Russian patent published in 2009 - IPC G01S17/02 

Abstract RU 2348056 C2

FIELD: physics, communications.

SUBSTANCE: claimed invention concerns optic electronic devices for two-way optic communication. Device includes emission source, flat reflector, blister, screen, receiving objective lens of laser emission, photoreceiving device, diaphragm installed in back focal plane of receiving objective lens. Light flow from emission source reaches flat reflector, is reflected and passes through blister. Central part of light flow is reflected from blister in direction of photoreceiving device and detained by screen, while a beam reflected from blister and passing over screen edge reaches diaphragm edge.

EFFECT: enhanced protection of device from internal blinding without increasing dimensions of laser emission receiving objective lens, expanded functional capacities.
