Performance of optical hologram written on silver halide film and its reconstruction

Performance of optical hologram based on silver halide film as well as its reconstruction is studied. Firstly, the principle of holographic imaging is introduced. Secondly, the process of optical hologram written on silver halide and image reconstruction are represented. It consists of four steps which are construction of optical written system, exposure and recording, developing and fixing, and optical reconstruction. Then repeating experiments on objects with different materials, different depths and different quantities are conducted. The effects of experimental parameters on reconstruction performance are studied, such as exposure time, developing time and intensity ratio between object wave and reference wave. The results show that experimental environment, system stability, light path, exposure time, developing time and the remaining details are key factors in the experiment.
