Abstract
A 3D imaging system includes a light source arranged to illuminate a scene with at least one optical pulse including light of at least two discrete wavelengths; an optical detector including an array of detection elements; and an optical modulator interposed in the optical path between the scene and the optical detector, the modulator being arranged to differentially amplitude modulate the two wavelengths in the reflected portion of the optical pulse as a function of time.
