    摘要: The present invention is directed to an apparatus and method for bistatic laser range imaging. The apparatus utilizes two light sources, two receivers, a demodulator and an image processor such that a three dimensional image is produced. The method includes generating beams of intensity modulated light, one toward a target, another toward a receiver. The light toward the target reflects from the target toward another receiver. The modulation envelopes of the beams of light are demodulated into components, the components digitized, then decimated, and a three dimensional image is constructed from the digitized components.

    摘要: An optical imaging system and method for use in a degraded visual environment is provided. A wideband modulated laser pulse is transmitted from a first location through a medium toward a target object. An input of the transmitted wideband modulated laser pulse is detected by an optical receiver. A target modulated laser pulse, reflected from the target object is detected by the optical receiver. The transmitted and reflected laser pulses are filtered by a bandpass filter, based on a predetermined modulated frequency range. The filtered transmitted and reflected laser pulses are digitized by an analog-digital converter. The digitized transmitted laser pulse is correlated with digitized reflected laser pulse by a digital matched filter, wherein the matched filter produces a passband matched filter output. A range of the target object is determined based on the matched filter output.
