Real-time holographic camera system

The holographic camera system for surface-relief hologram multiple reversible registration is presented. Photosensitive media is a single-layer photothermoplastic polymer on a glass substrate with conductive layer. This exclude a charges accumulation in the polymer volume and permits to realize an efficient enhancement of latent electrostatic image and its fast pulse heating development. The processes of charging, photogeneration, carriers transport, fast development and erasing, image enhancement were studied in detail and optimized. In order to improve some defects of photothermoplastic recording, originating from influences of circumstances and recording conditions, some new processes were developed: 1) fast charging with pulses corona in closed dielectric volume, 2) optoelectronic enhancement of electrostatic image 3) fast pulsed development with automatically controlled temperature rate, The dust-proof recording camera with built-in highvoltage power supply, thermo- and photosensors was designed to meet the needs of real-time or multiple-exposure interferometry, holographic training recording, holographic storage systems, correlation investigations and pattern recognition.
