Description: Technical report
Abstract: There is a program objective to systematically evaluate photosensitive recording materials that can be used in holographic and other coherent optical systems. In association with this, a detailed literature search was undertaken in which considerable information was obtained and compiled in this report. However, the recent literature describing the recording materials, particularly the nonsilver recording materials, is often confusing or incomplete. Very little detail is given about the chemistry, mechanisms, and processes of these materials with a view toward developing particular materials for use in holography. An objective of this report is to describe these aspects of the recording materials in a way that will aid in their future development and use in holography. Over 100 references were reviewed that treat electrostatic imaging materials, photoresists, hardened dichromated gelatin, photopolymers, photochromic materials, and bleached silver halide materials. Subcategories include Scott Graphics TEP film; photoplastic film; diazos, diazo-oxides and azides; Shipley's AZ 1350 positive photoresist; Hughes-NRC, DuPont and Bell Laboratories photopolymers; photochromic lithium niobate; and different halide bleaches for silver halide bleached holograms. The report compares a number of the characteristics of the different classes of holographic recording materials. Problems associated with the recording materials are described, and those material properties that enable use in important applications are pointed out. The not too well known chemistry of certain well known recording materials is also described.
