Instant holographic portrait printing system

An instant holographic portrait printing system has been developed. The system consists of a capturing camera, a high-speed image processing device, and a desktop one-step holographic stereogram printer. It takes less than 3 minutes to obtain a horizontal parallax 3D image 78 mm X 59 mm on DuPont photopolymer film HRF700X071-20, including capturing and image processing time. Since the holographic stereogram printer is designed for easy operation under non-laboratory conditions, an anti-vibration table or a dark room is not required. We describe several key technologies as well as a practical method for evaluating the image quality produced by one-step hologram printers.
