Active imaging system and method
View Patent ↗An active imaging system includes a laser transmitter configured to emit light in a plurality of beamlets. A sensor is configured to receive light from the beamlets. A processor is communicably coupled to the sensor and configured to compute images of objects illuminated by the beamlets.
1. A method for imaging an object, the method comprising;
emitting three beamlets through a first set of apertures from a laser transmitter to illuminate the object;
detecting the laser light scattered from the object;
emitting three beamlets through a second set of apertures from a laser transmitter to illuminate the object;
detecting the laser light scattered from the object;
computing a speckle intensity and phase difference frames of light detected for each set apertures;
combining the speckle intensity and phase difference frames of light detected for each set apertures to generate a single set of refined intensity and phase difference estimates;
reconstructing the wavefrom from the refined intensity and phase difference estimates; and
forming a speckled intensity image of the object.
