A multichannel laser radar has a laser array transmitter for generating a multiple laser beam array and a multichannel laser beam receiver for receiving reflected multiple laser beam array signals transmitted by said laser array transmitter. The multichannel laser beam receiver has a plurality of optical fibers coupled to a plurality of multichannel optical receiver photonic hybrid circuit boards for receiving reflected signals and processing the received signal range information and forming an image therefrom. Each circuit board has at least one detector assembly mounted thereon and each detector assembly has a plurality of photodetectors mounted to receive one end of each optical fiber so that a multichannel laser radar generates and receives multiple laser beams and parallel processes the received multiple laser beams to generate an image therefrom. Each detector on the detector assembly is mounted in a microcage having an opening therein for mounting the one end of one optical fiber and each optical fiber has a ceramic ferrule mounted on the end thereof shaped to fit into an opening in the microcage to allow the rapid attachment and alignment of the optical fiber ends relative to the photodetector.
