Paper Abstract

Solid-state imagers will displace electron-beam scanned imagers in applications which conventional TV does not satisfy. These are imaging from a moving platform like a weather satellite, imaging requiring very large intrascene dynamic range, imaging of very low contrast scenes and imaging in the infrared. In very low light level imaging, "photon counting" techniques with an ICCD can eliminate problems of dark current and preamplifier noise to provide high signal-to-noise ratio for improved radio-metric accuracy. At present, solid-state imagers lead for large effective dynamic range, maximum signal-to-noise ratio, free-dom from lag, geometric fidelity and metricity, and stability of characteristics, as well as for compactness, long life, and low operating voltages. Tubes lead for the greatest number of resolvable elements per frame, for producing images with better element-to-element uniformity, and for maximum output data rate on a single terminal.
