PURPOSE:To reproduce a polychromatic stereo image of an object, by irradiating the object by plural kinds of coherent lights whose wavelength is different from each other, and recording the interference fringe of said plural kinds of coherent lights, and each reference light having reference phase of each coherent light, at every wavelength. CONSTITUTION:A light source 101 of plural kinds of coherent lights whose wavelength is different from each other, and an optical filter 7 by which each microscopic part of constitution makes only one wavelength light among the lights from the light source 101 pass through are provided. If the light source 101 generates coherent lights of the three primary colors, each microscopic part on the filter 7 makes one primary color among the 3 primary colors pass through, and by its composition, an image of a natural color can be obtained. When a sensitized interference fringe is developed to a photosensitive body 5, an interference fringe corresponding to the microscopic part of the filter 7 is obtained, and when observation is made by use of the same filter as the filter 7 in this case, a stereo image 40 of an object 4 can be reproduced polychromatically. |
