Abstract
The effect of environmental humidity on the photosensitivity and real- time diffraction efficiency has been studied in dichromated polyvinyl alcohol (DC-PVA) films with and without external electron donors. High relative humidity has been found to significantly improve the photosp eed and the real-time diffraction efficiency for almost all of the stu died formulations, The results and possible photochemical reactions in the recording mechanism are briefly discussed.
