Paper Abstract

The photothermoplastic (PTP), photo- and thermoplastic molecular heterostructure materials, which are based on the new principles ofthe donor-acceptor sensibilizations, real-time optical processing methods, the PIP recording cameras, and optical information processing devices with new properties are considered. It is shown that such molecular heterostructure materials have high values of photosensitivity (20 to 100 ASA) and line resolution (above 600 line pairs/mm) and reversibility of over 1000 cycles. For a consistent recording regime a high reproducibility of parameters is achieved. The practical applications of PIP recording for operational holographic memory devices and optical modulation and bit recording systems are analyzed.
