Abstract

WIPOI PCT () Title: APPARATUS AND METHODS FOR IMAGING 120 Process a speckle image associated with an object with a plurality of point spreading functions to retrieve, for each point spreading function of the plurality of point spreading functions, information associated with the object from the speckle image, wherein the each point spreading function is different from another point spreading function of the plurality of point spreading functions in at least one attribute, and wherein the information is associated with a portion of the object at least substantially corresponding to the at least one attribute associated with the each point spreading function FIG. 1B (57) : According to embodiments of the present invention, an apparatus for imaging is provided. The apparatus includes a processor, and a memory coupled to the processor, the memory having stored therein instructions, which when executed by the processor, cause the processor to process a speckle image associated with an object with a plurality of point spreading functions to retrieve, for each point spreading function of the plurality of point spreading functions, information associated with the object from the speckle image, wherein the each point spreading function is different from another point spreading function of the plurality of point spreading functions in at least one attribute, and wherein the information is associated with a portion of the object at least substantially corresponding to the at least one attribute associated with the each point spreading function. Additional apparatus for imaging, and methods for imaging are also provided.
