Intensified Self-Scanned Array Technology Review

The purpose of this review is to describe the general status of the intensified self-scanned array technology area. Since the invention of CCDs in 1970, a wide variety of different types of self-scanned arrays (CCDs, CIDs, and photodiode arrays) have been used with photoelectronic imaging detectors to produce line-scan and TV raster-scan output signals for spectroscopic, facsimilie, low-light-level TV, and many other applications. Both optical input and electron-bombardment mode self-scanned array (SSA) readout methods have been employed. The advantages of using a photocathode as the prime detector, and microchannel plates for high-gain, are discussed. A major part of this review is to describe the various types of image tube intensified SSA cameras and instruments that have been made. Finally, some of the possibilities for new detector designs, based on the intensified SSA technology, are presented.
