Abstract
Solid-state imagers can displace electronic beam scanned imagers primarily in applications which con-ventional TV has not satisfied. Included are imaging from a moving platform like a weather satellite, imaging with very large intrascene dynamic range, imaging of very low contrast scenes including imaging in the infared where solid-state arrays in optomechanical scanners provide basically better performance and TDI techniques are increasing their advantage, and very low light imaging where "photon counting" techniques using an ICCD with an external computer memory can eliminate problems of dark current and of preamplifier noise in long time exposures and provide higher signal-to-noise ratio for improved radio-metric accuracy. In direct comparison, solid-state imagers lead for larger effective dynamic range, greater maximum signal-to-noise ratio, freedom from lag, geometric fidelity and metricity, and stability of characteristics, as well as the obvious 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.
