The photodegrdn. of the dyes in the polymer film was due only to the absorption at 254 nm. .

Applications of photoanisotropic polymer films in optical information processing and as nonlinear optical storage media

Applications of photoanisotropic polymer films in optical information processing and as nonlinear optical storage media. Fleck, B.; Wenke, L.

DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The use of optical interferometric measurement techniques for the visualization and characterization of transient processes in transparent media and the evaluation of dynamic deformations is of increasing interest in many branches of industry and research. Methods like holog. interferometry (real-time, double exposure) have the disadvantage that the handling of the storage media (photo plates, thermoplastics) is difficult and expensive devices are needed (for instance thermoplastic cameras). Therefore one aim of optics research is the development and the implementation of novel optical storage media which are easy to handle and have potentially low cost. Furthermore a great no. of modern optical methods require coherent electromagnetic waves, but the information is often carried by incoherent illumination (CCD-cameras) or by laser radiation with wavelengths (due to the absorption characteristics of the object under investigation) which are not suited for current materials or devices. For that reason the conversion of information from one wave to a wave with another wavelength or from incoherent light to coherent light is necessary. In this paper we describe two possible applications of different photoanisotropic polymer samples. 9011-14-7 and 3180-81-2 are cas registry numbers. These chemicals are also mentioned in this article. At first these samples are used as holog. storage media in real-time holog. interferometry and at second as nonlinear media for incoherent-to-coherent conversion. The first example includes the principal exptl. setup. The second example shows the possibility of incoherent-to-coherent conversion of information. The intensity transfer function of this conversion process is calcd. .
