1. A light detection and ranging (LIDAR) system for a vehicle, the LIDAR system comprising:
a transmitter configured to emit a transmit beam to an object;
a receiving pixel that includes a grating coupler and is configured to receive a returning beam reflected from the object through the grating coupler; and
a beam displacement apparatus disposed relative to the receiving pixel, wherein the beam displacement apparatus is configured to introduce one of a first displacement associated with a first direction of rotation of an optic element of the LIDAR system or a second displacement associated with a second direction of rotation of an optic element of the LIDAR system to the returning beam to compensate for a spacing between the transmitter and the receiving pixel.
