摘要
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.
