The Optical Data Processing Family Tree

The historical development of the field of optical data processing can be represented in the form of a tree. Like a tree, the field has deep roots, a strong trunk, major branches that subdivide into smaller limbs, and new growth. In many cases the branches intertwine. The structure of this tree is the topic of this article. Keep in mind, however that the picture presented here is a personal and subjective one. This is always the case in any evaluation of past developments and speculation about the future.
