Abstract
In many sensor systems, simultaneous sightings with two independent focal planes are required. A two-color experiment is an example. When the sensor has a mosaic focal plane with thousands or millions of detectors, precise alignment between each pair of corresponding detectors is impossible. The individual chips on each focal plane will be offset from the desired position. These offsets can be in two linear directions, a rotation, or a combination of these. The effect of these offsets depends both on the distribution of the energy in the observed scene and on the parameters of the sensor. In this paper, these effects are analyzed. A specific example is shown to demonstrate the effects and method of evaluation. No discussion is included about how to align the focal planes, how to measure the boresight errors, or the sensor rigidity requirements.
