Real time study of development process in holographic emulsions

In this paper we present the theoretical and experimental study using a rea l time technique for the measurement of the optical density when the emulsi on is developing. Good agreement was observed between theory and experiment . We exposed an Agfa Gevaert 8E56HD emulsion with an Argon laser tuned at 5 14 nm and we measured the variation in optical density when the emulsion wa s put into the developer bath at 20 degrees C. This method allows us to stu dy the dynamics of different developers at different energy of storage. It also provides a way to optimize the composition of developers as a function of the chemical composition, temperature and other secondary factors as su peradditivity and non-linear processes.
