Abstract
The geometrical design characteristics of multiple-image holograms are evaluated. A figure of merit expressing these characteristics as a function of the hologram diameter and the distance between the hologram and the image plane is developed. This value is then used to compare two designs which are capable of forming several hundred interconnections. The results indicate that these connections can be formed between points on the substrate separated by 2–3 cm provided that the holograms are separated from the substrate plane by 0.5–1 cm. Each hologram design is experimentally demonstrated in bleached photographic emulsions.
