Lidar detection methods and systems with optical fiber array

A LiDAR system for detecting objects in a region of interest, the system comprising:

• a radiation source for emitting a plurality of output beams;
• a microelectromechanical (MEM) component having a reflective surface for receiving the plurality of output beams and for reflecting the plurality of output beams towards the region of interest, the MEM component configured to oscillate about a first oscillation axis by a first oscillation amplitude to modulate each one of the plurality of output beams by a vertical interval along a vertical axis in the region of interest;
• a detection system for detecting a plurality of input beams from the region of interest, the detection system comprising:
• a fibre optic array arranged to transmit the plurality of input beams to at least one photodetector, the fibre optic array comprising a plurality of optical fibres, each optical fibre having a receiving end, the receiving ends of the plurality of optical fibres being arranged in a two dimensional array;
• and
• a receiving lens configured to move to focus each different input beam of the plurality of input beams to a receiving end of a different optical fibre of the fibre optic array, wherein a distance between the receiving lens and the receiving ends of the plurality of optical fibres in the fibre optic array comprises a focal distance of the plurality of input beams.
