METHOD FOR PHOTOGRAPHING ORIGINAL PICTURE OF PLANE TYPE HOLOGRAPHIC STEREOGRAM

摘要

PURPOSE:To obtain an original picture which is resolved up to a fine part while a view area is widened by rotating or fixing a camera, placing a body on a rotary table and rotating it, and specifying the angle of rotation for each frame. CONSTITUTION:A plane type holographic stereogram is composed of many original pictures which have parallex continuously and when a rainbow hologram is manufactured, the camera 61 rotates around the body 61 or is fixed and the body 61 is placed on the rotary stage 65 and rotated. In this case, dtheta=A.COS2theta, where theta is the angle of rotation and A is a constant. This is a rotating method in which dl is constant when the camera moves on a straight line 64. This photographing method is employed to enable the body to be photographed at shorter distance within the range of the visual field of a lens 63, so the image is resolved sufficiently finely and a sufficiently wide view angle 67 is obtained.
