20110199621SINGLE-TRANSDUCER, THREE-DIMENSIONAL LASER IMAGING SYSTEM AND METHOD - Disclosed herein are a system and method for three-dimensional imaging using a single transducer. A laser in a transmitter emits a sequence of short pulses, each of which is at a different center wavelength (frequency). A dispersive element in the transmitter spatially separates the pulses according to wavelength, with different pulses mapped to different spatial locations in a target volume via a lens. The pulses travel to the target, which scatters or back-reflects the pulses towards the dispersive element via the lens. The lens collects the returned pulses and transmits them to a single transducer via the dispersive element. The transducer measures the time of arrival for each returned pulse. Because the arrival time depends on the range to the object in the portion of the target illuminated by the corresponding emitted pulse, the measured arrival time can be used to reconstruct a 3D (angle-angle-range) image of the object.08-18-2011
