An example lidar system includes a housing defining an interior space. The housing includes at least one optical window. The lidar system also includes a rotatable mirror assembly disposed within the interior space. The rotatable mirror assembly includes a transmit mirror portion and a receive mirror portion. The lidar system additionally includes a transmitter disposed within the interior space. The transmitter is configured to emit emission light into an environment of the lidar system along a transmit path. The lidar system also includes a receiver disposed within the interior space. The receiver is configured to detect return light that is received from the environment along a receive path. The lidar system additionally includes at least one optical baffle configured to minimize stray light in the interior space.

Split window and baffling

The present disclosure relates to devices, lidar systems, and vehicles that include optical redirectors. An example lidar system includes a transmitter and a receiver. The transmitter includes at least one light-emitter device configured to transmit emission light into an environment of the lidar system. The receiver is configured to detect return light from the environment and includes a plurality of apertures, a plurality of photodetectors, and a plurality of optical redirectors. Each optical redirector is configured to optically couple a respective portion of return light from a respective aperture to at least one photodetector of the plurality of photodetectors. At least one of the optical redirectors includes an optically isolating coating.

Optical redirector device

The present disclosure relates to systems and devices having a rotatable mirror assembly. An example system includes a housing and a rotatable mirror assembly. The rotatable mirror assembly includes a plurality of reflective surfaces, a shaft defining a rotational axis, and a mirror body coupling the plurality of reflective surfaces to the shaft. The mirror body includes a plurality of flexible support members. The rotatable mirror assembly also includes a coupling bracket configured to removably couple the rotatable mirror assembly to the housing. The system also includes a transmitter configured to emit emission light into an environment of the system after interacting with at least one reflective surface of the plurality of reflective surfaces. The system additionally includes a receiver configured to detect return light from the environment after interacting with the at least one reflective surface of the plurality of reflective surfaces.
