Abstract
Described are various configurations for transmitting and receiving optical light using a shared path ranging system. The shared path ranging system can include an optical router (e.g., an optical coupler) coupled to a grating to transmit light to a physical object and receive light reflected by the physical object. The shared path ranging system can include rows of routers and gratings in a two-dimensional configuration to transmit and receive light for ranging purposes.
