Abstract
The present disclosure provides systems, methods and apparatus for producing holographic displays using an electromechanical systems device. In one aspect, the method can be implemented to allow for simultaneous modulation of phase and amplitude of light in a display device composed of a plurality of pixels. A light source can provide sufficiently coherent light to a light guide, which can direct the light to a plurality of reflective members. The reflective members can reflect the light to a pinhole-lenslet array. The combination of the pinhole-lenslet array and the reflective members can act as a spatial light modulator, modulating the phase and amplitude of the light reflected by the reflective members. The lenslet can focus the light to a plane at the opening of the pinhole, wherein the light can exit the pinhole to be viewed in combination with light from additional pixels, and can be viewed as a holographic image.
