摘　　要：本文采用普通一步彩虹全息的记录光路,多次曝光拍摄物体多个侧面的彩虹全息图,从而可以克服一步彩虹全息视场受成像透镜相对孔径限制的缺点。A rainbow hologram of several sides of an object is synthesized with the conventional one-step rainbow holography by multi-exposures, therefore, the viewing angle is no longer lestricted by the relative aperture of the imaging lens. By choosing properly the recording parameters of seperate exposure a satisfactory image with large viewing angle is obtained.

关 键 词：彩虹全息术 大视角 渐晕效应
