Abstract

A method of combining holograms or phase images of an object is disclosed, where attributes of the data used to record two phase images of overlapping portions of the surface of an object are compared and used to match pixels of the two recordings. A relative tilt angle and direction correction is added, and a third phase image is generated. Phase images of objects which are too large to be imaged in an interferometric imaging system can thus be produced.
