Method of digital holography WFOV imaging based on phase stitching
摘要
Abstract
A method to enlarge the field-of-view in digital holography imaging based on sub-aperture phase stitching tech-nique is proposed in this paper. The part information of an object is recorded by the off-axis digital holographic interferometer and the part phase image of the object is picked up by means of the Fresnel diffraction algorithm. Then the phase profiles in all the sub-regions are stitched together with the error averaging method,while the tilt of the stitched map are calculated and elimi-nated to obtain the orthoscopic profile of the whole surface. It was validated by the reflective resolution plate USAF 1951. The proposed method breaks away from the limits of the area of the CCD and expands the digital holography imaging field-of-view while the resolution is kept in the same level as that of the traditional methods.关键词
