Patent ID: 8581979

Claim:
A system for constructing high resolution images, the system comprising: a beam splitter assembly; reflecting an input light beam to generate a splitting beam; a light intensity modulator; modulating an intensity of the splitting beam to generate a modulating beam; including a predetermined noise, wherein the modulating beam is emitted onto an object to generate a modulating image; a grating, wherein the modulating beam passes through the grating to generate an interference fringe projecting onto the object; an image capturing module; obtaining a plurality of modulating images; a controller; generating a grating-translocation signal to control the translocation of the grating; and an image processing module; analyzing the modulating images to generate a high resolution image, wherein the image processing module constructs a phase difference of the object according to the modulating images prior to the translocation of the grating or after the translocation of the grating.
