Abstract
A preferred embodiment of the optical reconstruction assembly 50 in which the assembly 50 includes an assembly housing 52 that is a unitary unit for supporting a spatial filter 72 and a light source 74 in a single plane at the optical length 'L' from a collimating lens 86. A liquid container 88 is mounted to the assembly housing 52 containing the holographic liquid 90. The light source 74 and the spatial filter 72 are spaced a fixed distance 'A' which is less than the optical diameter 'D' of the collimating lens 86.
