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; and

    at 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.
