Abstract:
1. A method for producing 3D images, comprising: providing a pixel-by-pixel map over a preselected aperture of relative phases for coherent light scattered by a desired scene or transmitted through the desired scene; translating independently translatable micro-mirrors of a reconfigurable mirror array such that the micro-mirrors are positioned with respect to a reference plane to produce reflected light whose wave front has the pixel-by-pixel map over the preselected aperture in response to the array being illuminated with a coherent visible light beam; and illuminating the reconfigurable mirror array with the coherent visible light beam to produce a 3D image of the desired scene with the reflected light; and wherein an effective lateral linear dimension of the micro-mirrors is smaller than five times a wavelength of the light of the visible light beam.
