Lidar system with integrated frequency shifter for true doppler detection
A vehicle, Lidar system and method of detecting an object is disclosed. The Lidar system includes a photonic chip having a laser, an on-chip frequency shifter, a combiner and a first set of photodetectors.

An opaque coating on the back side of an aperture element coupled to the polarizing beam splitter is patterned to provide a transparent aperture. At least a portion of light returning to the LiDAR apparatus from the region being observed is directed by the polarizing beam splitter, through the transparent aperture in the opaque coating on the aperture element, through the at least partially reflective optical element to an optical detector mounted on the substrate.
Depth image acquiring apparatus, control method, and depth image acquiring system
It is intended to promote enhancement of performance of acquiring a depth image. A depth image acquiring apparatus includes a light emitting diode, a TOF sensor, and a filter. The light emitting diode irradiates modulated light toward a detection area becoming an area in which a depth image is to be acquired to detect a distance. The TOF sensor receives incident light into which the light irradiated from the light emitting diode is reflected by an object lying in the detection area to become, thereby outputting a signal used to produce the depth image. The filter passes more light having a wavelength in a predetermined pass bandwidth than light having a wavelength in a pass bandwidth other than the predetermined pass bandwidth of the light made incident toward the TOF sensor. In this case, at least one of the light emitting diode, the TOF sensor, or arrangement of the filter is controlled in accordance with a temperature of the light emitting diode or the TOF sensor. The present technique, for example, can be applied to a system for with international search report acquiring a depth image by using a TOF system.
