SYSTEMS AND METHOD OF HIGH RESOLUTION THREE-DIMENSIONAL IMAGING

摘要

Embodiments of the invention provide systems and methods for three-dimensional imaging with wide field of view and precision timing. In accordance with one aspect, a three-dimensional imaging system includes an illumination subsystem configured to emit a light pulse with a divergence sufficient to irradiate a scene having a wide field of view. A sensor subsystem is configured to receive over a wide field of view portions of the light pulse reflected or scattered by the scene and including: a modulator configured to modulate as a function of time an intensity of the received light pulse portion to form modulated received light pulse portions; and means for generating a first image corresponding to the received light pulse portions and a second image corresponding to the modulated received light pulse portions. A processor subsystem is configured to obtain a three-dimensional image based on the first and second images.

1. A three-dimensional imaging system, comprising:
an illumination subsystem configured to emit a light pulse with a divergence sufficient to irradiate a scene; a sensor subsystem comprising:
a receiving lens having a predetermined image plane and a predetermined pupil plane, the receiving lens configured to receive a portion of the light pulse reflected or scattered by the scene, whereby outputting a received light pulse portion having a duration;a modulator configured to modulate as a function of time an intensity of the received light pulse portion to form a modulated received light pulse portion, wherein the modulator is not located in the image plane or pupil plane of the receiving lens; andat least one imaging sensor array configured to generate a first image and a second image in response to the modulated received light pulse portion; and a processor subsystem configured to obtain a three-dimensional image based on the first and second images.
