A CMD Image Sensor

An Approach to High-Resolution Imaging

Abstract

This paper introduces examples of CMD high-resolution cameras and analyzes the factors that limit the performance of CMD and other imagers. The necessary conditions for achieving higher resolution are explained. Making the quantum efficiency near unity is the one and only method to improve the optical performance. In electronics, the main subjects are noise suppression and power saving. It is concluded that CMDs and some APSs (Active Pixel Sansors) are superior to the CCD family from the viewpoint of wide bandwidth and low power consumption.
