Abstract

Imaging systems often create undesirable signals such as narcissus, microphonics, shading, etc. It is important to reduce these unwanted signals to an acceptable level during the system design process. To do so, one must develop a model that considers the perceptibility of the unwanted signal to an observer. Consequently, the spatial and temporal characteristics of the eye/brain must be considered. An example is provided that shows a technique to determine the threshold of undesirable signals while considering the spatial and temporal characteristics of the observer.
