Abstract
Laser light pulsed to illuminate and reflect from at least one object is received at a digital micro-mirror device including an array of mirrors each of which may be selectively controlled to be oriented to either reflect incident light onto a detector or not. The detector outputs a signal representative of an amount of light sensed. By applying M spatial patterns to the mirrors, each in synchronization with one pulse from the laser, and storing sampled signal values from the detector output at each of K times following a pulse from the laser, the collected information may be used to reconstruct K images each using all M spatial patterns and stored sampled signal values corresponding to a respective one of the K times. Each of the K images corresponds to a different range to the digital micro-mirror device, such that the system may be employed as a range finder.
