Abstract
In one embodiment, a light detection and range (LIDAR) device includes an array of light transmitting and receiving (TX/RX) units arranged to sense a physical range associated with a target. Each of the light TX/RX units includes a mounting board having a light pass-through opening and a light emitter mounted adjacent to the light pass-through opening. The light emitter is configured to emit a light beam towards the target according to a transmitting path. The LIDAR device further includes a light detector positioned behind the mounting board to receive at least a portion of the light beam reflected from the target through the light pass-through opening according to a light receiving path. The light transmitting path and the light receiving path are substantially in parallel and close to each other.
