Abstract
In one embodiment, a three-dimensional LIDAR system includes a light source (e.g., laser) to emit a light beam (e.g., a laser beam) to sense a physical range associated with a target. The system includes a camera and a light detector (e.g., a flash LIDAR unit) to receive at least a portion of the light beam reflected from the target. They system includes a dichroic mirror situated between the target and the light detector, the dichroic mirror configured to direct the light beam reflected from the target to the light detector to generate a first image, wherein the dichroic mirror further directs optical lights reflected from the target to the camera to generate a second image. The system includes an image processing logic coupled to the light detector and the camera to combine the first image and the second image to generate a 3D image.
