Paper Abstract

The first electro-optical system that generated hardcopy output was the photographic camera. Its invention is generally accredited to the French physicist Joseph Nicephore Niepce (1765 - 1833) who made the first permanent image in the camera obscura, shown in Figure 1. He exposed a light sensitive metal plate in the camera, and then used an engraving process to "fix" the image. This photograph was made 160 years ago in 1826 and still exists today. Fundamentally we are still trying to perform the same function, to transfer a real scene to a hardcopy that can be handled. Since then it has been made faster, with higher resolution , over wider environmental ranges , with an operating requirement of transferring the imaged scene, target or observation to somewhere else for use.
