Fiber-based transmitter and receiver channels of light detection and ranging systems

A light detection and ranging (LiDAR) system comprising:

• a plurality of transmitter channels comprising transmitter optical fibers disposed in an optical fiber housing at a pre-determined pitch from one another;
• a collimation lens positioned to be optically coupled to the plurality of transmitter channels to receive a plurality of transmission light beams transmitted from the transmitter optical fibers;
• a collection lens disposed to receive and redirect return light generated based on the plurality of transmission light beams;
• and
• an optical beam-shifting system optically coupled to the collimation lens;
• wherein:
• the collimation lens is configured to collimate the plurality of transmission light beams;
• a combination of the plurality of transmitter channels and the collimation lens is configured to transmit a plurality of collimated transmission light beams at an angular separation from each other to provide an angular channel spacing that is related to the pre-determined pitch;
• the collimation lens is positioned on a side of the collection lens to redirect the plurality of transmission light beams to the optical beam-shifting system;
• and
• the optical beam-shifting system is configured to redirect the plurality of collimated transmission light beams such that at least one of redirected collimated transmission light beams is positioned within an optical receiving aperture of the collection lens.
