Color electronic camera including photosensor array having binary diffractive lens elements
First Claim
1. A color electronic camera, comprising:
- a housing; and
a photosensor array that is supported by the housing and includes a plurality of photosensor units for aggregately sensing a light image, each photosensor unit comprising;
a two-dimensional binary diffractive lens for diffactively forming three substantially identical segments of said light image in three different colors on three rotationally spaced areas of a surface respectively; and
three photosensors disposed on said surface at said three rotationally spaced areas for receiving said segments respectively.

Abstract
A camera comprising various arrangements for employing optical elements in association with photosensitive elements are described. In some of the arrangements, the optical elements are formed integrally with a substrate containing the photosensitive elements. In other arrangements, an optical element is mounted to a package, or the like, containing the substrate and photosensitive elements. In other arrangements, two or more optical elements are employed, including conventional refractive elements, refractive focusing elements, and refractive beam splitting elements. Utility as solid state image sensors is discussed. Utility for monochromatic and color imaging is discussed. Various devices based on such camera arrangements and methods of making same are discussed.
