A key source of digital images is the electro‐optical imaging sensor. The basic characteristic that identifies a digital electro‐optical sensor is conversion of reflected or emitted light from a scene or object into a digital image signal. Examples include television cameras with digital output, and scanning or staring cameras with digital output. We describe general system design techniques to derive optimum imaging sensor specifications, and we offer examples for two applications. One example application is for terrestrial thermal imaging of nearby objects, such as vehicles. The other example is a sensor to create a color image of small targets in low‐light, such as an automobile license plate from a distance of several meters.©1993 John Wiley & Sons Inc
