We consider a optical system as a communicated channel, it consisted of many
element transfer information. Then, it`s very important to know how it is operate
well for specific proposal. Photosensitive material is important part of many optical
systems, its OTF characteristics need to be clearly understood if the performance of
the overall system is to evaluated. We tested a holographic photosensitive material, basically similar to photographic material. Sayce logarithm test chart which has a variable spatial frequency squarewave test pattern. We used one of square bar, as a edge. In order to determine OTF, the first step is to convert the microdensitometer trace to an equivalent effective exposure trace by means of the characteristic curve and the second step is to analyse the effective exposure data to know image quality. As a result, we can evaluate a holographic material to use a OTF concept except a diffraction efficiency.
