DEVICE FOR RECORDING HOLOGRAM AND HOLOGRAM CARD MANUFACTURED BY DEVICE FOR RECORDING HOLOGRAM

摘要

PURPOSE: A device for recording a hologram and a hologram card manufactured by a device for recording a hologram are provided to improve the recording efficiency and prevent illegal copy of personal information of a user. CONSTITUTION: Laser beams dispersed on a video plate(100) enter a glass film(154) of a hologram film(152). Other laser beams reflected from a concave mirror(146) enter a photo sensitive material(156) of the hologram film. The dispersed beams enter the photo sensitive material by transmitting the glass film. The laser beams of objective wave dispersed on the video plate and transmitted to the photo sensitive material interfere with the laser beams of reference wave directly entered the photo sensitive material, thereby forming a hologram interference pattern on the photo sensitive material. Personal information(102) of the video plate is contained in the hologram interference pattern of the photo sensitive material.
