Abstract
Apparatus and methods for determining the distance to an object by detecting a reflected light beam. A light emitter emits a light beam. An optical fiber is mounted to direct the light beam as an output light beam of the optical fiber. An actuator is coupled proximate a distal end of the optical fiber, for moving the distal end of the optical fiber in a desired pattern. Collimation optics are mounted to intercept the output light beam of the optical fiber and collimate the output light beam of the optical fiber. A photodetector is mounted to receive a reflected light beam after reflecting off an object in an external environment. A control system determines a distance to the object based on an elapsed time between emission of the light beam and a detection of the reflected light beam by the photodetector.
