Abstract

A compact monostatic optical transmitter/receiver device simultaneously transmits an optical beam and collects returning light using a single lens or optical aperture. The system provides automatic alignment of the transmit and receive aperture and is compatible with fiber-coupled laser sources. Transmit light is emitted from a double-cladding fiber core while received light is coupled into the inner cladding of the same fiber. The transmit light propagating in the core and the received light propagating in the inner cladding are separated by the means of a diplexer comprised of a fused fiber coupler or a fiber-coupled micro-optic device.
