Abstract

A novel method for the determination of a camera system's overall performance is described. This method involves the use of new form of test chart, termed a Nyquist chart. A Nyquist chart is a deterministic pattern of bright and dark structures that are imaged onto an image sensor array at the time sensor array's (spatial) Nyquist frequency. Camera system parameters such as MTF at the Nyquist frequency, distortion, pixel aspect ratio, color filter array layout, color balancing, field of view, relative illumination, depth of focus, and Petzval curvature can be readily determined.
