Abstract

Noise and sensitivity measurements are compared for five intensified cameras used for airborne sensing of mines. Individual camera variations are discussed, as well as global similarities useful in camera modeling. The cameras generally have behaviors that closely match each other, but differ in sensitivity by factors of up to 12 for equal noise. The implication is that these intensified cameras-being short production-run items-display a great deal of individuality and that each camera must be carefully characterized before use. Reciprocity (product of radiance and exposure) and the variation of noise with radiance were also tested and found to be flat over three orders of magnitude, thus simplifying modeling.
