ABSTRACT:
A blur filter for use with a multi-element electro-optical sensor is formed with a plurality of diffractive elements positioned adjacent each other with each of the elements being comprised of uniformly spaced concentric diffractive features. The plurality of diffractive elements are secured in a plane near the sensing surfaces of a multi-element electro-optical sensor. Each element of the multi-element sensor has a plurality of sensing surfaces for receiving incident light from a plurality of diffractive features.
