Abstract
Dispersive imaging has been shown to be an effective technique to optically control aliasing in mosaic pattern color sensors. It can be adapted to all of the currently used color filter array patterns and sensor layouts. Depending on the sensor, residual uncompensated errors remain after the optical image is recorded. Results will be demonstrated for several sensor/filter combinations. These will be used to support the conclusion that pixels that are optimum for dispersive filtering produce smaller residual errors. Pixel geometries, color filter array patterns and spectral sensitivities could be produced to minimize these errors. The design of these sensors are discussed in this paper. Optimum solutions are proposed and analyzed. These proposed solutions are compared to imaging systems currently in use.
