Description of the invention (1) [Field of the invention] The present invention relates to a device and method for making a disc type composite holographic display film, especially a disc type composite holographic image that can be used to surround and view three-dimensional images. Device and method for showing films. [Background of the Invention] Composite holography (Mu 11 i ρ 1 e X ο ο 1 〇graphy) is a technology that uses laser to capture a three-dimensional image with a two-dimensional spatial depth of field, and is used to image the two-dimensional of a recorded object 1. The sensitization medium of an image is called a multiplex.

Hologram), holography is the use of laser light coherence (coherence) properties, the laser light source is divided into two light sources, the first light source shines on the surface of the object and reflects on the holographic film, this light source is called Object light (〇b′ec t wave), another one directly irradiated on the holographic film is called reference light (reference wave), the object light and reference light are irradiated on the holographic film at the same time to form an optical interference phenomenon, object light Contains only the light and shade data of the image, and the interference fringe further contains the position data. After exposure, the holographic negative film is a composite holographic image of the two-dimensional image of the recorded object. The reconstructed light source is projected on the completed composite hologram, and the three-dimensional stereoscopic image of the object will appear. Traditional compound holograms include the cylindrical type and the conical type. During the imaging period, a 1% holographic negative film must be used, or when a composite holographic image is produced, the composite holographic image must be reconstructed. The sheet is bent into a cylindrical or conical shape.
