Abstract
A holographic image forming system is provided. The use of an image slicing process and/or the arrangement of half-cylindrical lens in the optical path of an optical light wave and upstream of the film is effective to reduce the times of multiple exposures of the film. As a consequence, the brightness of the reconstructed image is enhanced.
Claims16
A holographic image forming system, comprising:
- an illumination unit for providing a coherent beam;
- a beam splitting unit for splitting said coherent beam into a reference beam and an object beam;
- a reference beam processing unit for receiving said reference beam and outputting a reference light wave with respect to said reference beam;
- an image generating unit for providing a first image of a target object;
- an object beam processing unit comprising an object beam imaging system for guiding said object beam to said image generating unit, thereby generating an object light wave, wherein said object beam imaging system comprises a half-cylindrical lens, and said object light wave carries an image information of said first image;
- and
- a film, wherein when said reference light wave and said object light wave are incident to said film, said reference light wave and said object light wave are interfered with each other to result in a plurality of interference fringes on said film, wherein said object light wave is directed from said object beam imaging system to said film through said half-cylindrical lens, wherein, exclusive of being located right on said focal plane distance, said film is located within a depth-of-field range around a focal plane distance of said object beam imaging system.
A holographic image forming system comprising an illumination unit, a beam splitting unit, a reference beam processing unit, an image generating unit, an object beam processing unit and a film, wherein said image generating unit further captures multiple image frames of said image of a target object with the preset number of capture pixels, and processes said multiple image frames with the preset number of projection pixels, then said processed multiple image frames are recorded on said film, wherein the number of projection pixels is lower than the number of capture pixels, and multiple image informations of said multiple image frames with the preset number of projection pixels are complementary to each other.
