Expansion of the Illumination and Reconstruction Areas in Reflection-Type Digital Holography Microscope System

Abstract

A modified Michelson interferometer-type digital holography microscope that employs two convex lenses was developed. This system maintains a plane reference wave and can change the illumination area of the objective beam incident to the object. We call this system the modified, reflection type digital holography microscope system (MRDHMS). We were able to increase the recording and reconstruction areas of the target object. We also studied the effective recordable and reconstructible areas of the charge-coupled device (CCD) using MRDHMS. (C) 2009 The Japan Society of Applied Physics.
