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 image enhancer that includes a laser for emitting an optical signal toward an object in a turbid medium, a modulator for modulating laser intensity of the optical signal, an RF source for driving the modulator and for providing a reference signal, an optical detector for detecting the modulated optical signal that is reflected from the object, the optical detector converting the reflected optical signal into an electrical signal, the electrical signal having RF and DC components, an I/Q demodulator for mixing the RF component of the electrical signal with the reference signal and producing in-phase and quadrature phase signal components that can be digitized and processed such that both contrast and range images of the object are produced.

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.
