Abstract
In one embodiment, a light detection and range (LIDAR) device includes a light source to emit a light beam to scan a range of orientations associated with a target scanning zone. The LIDAR device further includes a first microelectromechanical system (MEMS) mirror configured to receive and redirect the light beam towards to the target scanning zone. The first MEMs mirror is configured to tilt vertically and horizontally to redirect the light beam in a plurality of angles. The LIDAR device further includes a light detector to receive the light beam reflected from one or more objects located within the target scanning zone. The first MEMS mirror tilts multiple directions with respect to the light source to allow the light source to emit the light beam and the light detector to receive the reflected light beam to obtain multiple angular resolutions of the one or more objects.
