摘要： PROBLEM TO BE SOLVED: To easily measure a moving object by a digital holography method. SOLUTION: In digital holography image reproduction, an observed hologram image obtained in four phase-shift amounts by a tilt phase shift holography method is input and then image data of pixels whose observed data are lacked are estimated based on an equation of wave optics expressing optical intensity of the interference fringe of object light and reference light, in a hologram image obtained each four pixels for a phase shift amount. After that, in a complex amplitude hologram composed of observation data and estimation data, background noises are removed. Further, the reproduced light distribution in the reproduced image space is calculated from the complex amplitude hologram from that background noises are removed. COPYRIGHT: (C)2010,JPO&INPIT
