INTERFERENCE FRINGE DATA GENERATING DEVICE, INTERFERENCE FRINGE DATA GENERATING METHOD, AND INTERFERENCE FRINGE DATA GENERATING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an interference fringe data generating device which is capable of generating the image data of interference fringes after half-zone-plate processing at high speed, even when an object is virtually arranged in front of and behind of a hologram surface.;SOLUTION: The interference fringe data generating device 1 is equipped with an object information input means 2 which inputs the information of the light quantity of each of a plurality of points on the object with a three-dimensional position and a virtual interference fringe calculating means 4 which limits the diffusion of object light from each of virtual object points being the plurality of points on the object virtually arranged to the half in directions opposite to each other by the object light with which a virtual hologram surface virtually arranged is virtually irradiated from one side across the virtual hologram surface and the object light with which the virtual hologram surface is virtually irradiated from the other side, based on the information, by half-zone plate processing, to calculate interference fringe data being the image data of the interference fringes of the object light with reference light.;COPYRIGHT: (C)2009,JPO&INPIT
