Abstract: This technology relates to a system for preventing particle buildup on a sensor housing. The system may include a sensor housing including a first surface, a motor, and a spoiler edge. The motor may be configured to rotate the sensor housing around an axis. The spoiler edge may be positioned adjacent to the first surface and extended away from the first surface perpendicular to the axis of rotation of the sensor housing.

Abstract: The present disclosure relates to optical systems and methods of their operation. An example optical system includes an optical component and one or more light sources configured to emit a light signal. The light signal interacts with the optical component so as to provide an interaction light signal. The optical system also includes a detector configured to detect at least a portion of the interaction light signal as a detected light signal. The optical system additionally includes a controller configured to carry out operations including causing the one or more light sources to emit the light signal and receiving the detected light signal from the detector. The operations also include determining, based on the detected light signal, that one or more defects are associated with the optical component.

Abstract: The subject matter of this specification can be implemented in, among other things, a system that includes a light source to produce a first beam and one or more first optical elements to impart an orbital angular momentum (OAM) to at least some of a plurality of output beams obtained from the first beam. The system further includes an output optical device to direct the output beams towards a target object and a plurality of photodetectors to generate signals representative of a difference between an input phase information, carried by one or more beams reflected from the target object, and an output phase information, carried by one of local copies of the output beams. The system further includes a processing device to determine, using the difference between the input phase information and the output phase information, one or more orthogonal components of a velocity of the target object.
