Abstract: LiDAR systems and methods for detecting objects in a region of interest, the system comprising: a radiation source for emitting an output beam; an oscillating component having a oscillating component reflective surface for receiving the output beam, the oscillating component arranged to oscillate to modulate the output beam to a first spread beam having a first spread beam interval along a first spread axis; at least two static optical components having respective optical component reflective surfaces for receiving the first spread beam, the respective optical component reflective surfaces being angularly offset from one another such that: each one of the respective optical component reflective surfaces receives and reflects a respective portion of the first spread beam; the reflected respective portions together comprise a second spread beam having a second spread beam interval along a second spread axis which is larger than the first spread beam interval.

Abstract: An optical system and method for controlling the system, and a self-driving vehicle connected thereto. The optical system includes a housing; a first light source configured to emit light in a first wavelength band; a second light source configured to emit light in a second wavelength band different from the first wavelength band; a dichroic element configured for combining light from the first light source and the second light source into an output light beam to be scanned over a field of view; a scanning unit configured to direct output beam outwardly from the optical system, the scanning unit being disposed in the housing; a controller communicatively coupled with the scanning unit; and at least one sensor communicatively coupled with the controller and configured to sense light reflected off surrounding objects into the optical system.
