Experimental Research on Uniform Design-Based Optimization Conditions of Diffuse Holography

The diffuse reflection holography with holographic dry plate was used to make the hologram in this study. It can display three-dimensional image of the object by exposing, developing, fixing and stopping technologies. Uniform design with 4 investigated factors was investigated to optimize the parameters of the holography, including exposing time, developing time, the angle between object lights and reference lights, and the distance between objects and dry plates. The result shows that the object lights, reference lights angle, exposing time, and developing time have little effects on the results within the experimental parameter range for the holographic vases, while the distance should be within 10 cm. However, exposing time and developing time are very important for the holographic coins.
