Abstract
Abstract Methods of etching 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
82 words
A method of forming a color electronic image corresponding to a light image, comprising: arranging a plurality of lenses for each to diffractively form three substantially identical segments of the light image in three different colors on three spaced areas of a surface respectively; arranging three photosensors on said surface at said three spaced areas for receiving the three segments to generate electrical signals corresponding to respective ones of the segments and processing said electrical signals to produce the color electronic image.
Claim 2
Independent Claim
82 words
A method of forming a color electronic image corresponding to a light image, comprising: arranging a plurality of lenses for each to diffractively form three substantially identical segments of the light image in three different colors on three spaced areas of a surface respectively; arranging three photosensors on said surface at said three spaced areas for receiving the three segments to generate electrical signals corresponding to respective ones of the segments and processing said electrical signals to produce the color electronic image.
Claim 3
Dependent Claim
15 words
A method according to claim 1, wherein each lens is a circular binary diffractive lens.
Claim 4
Dependent Claim
23 words
A method according to claim 1, wherein the three spaced areas are substantially equally rotationally spaced from an axis of each lens respectively.
Claim 5
Dependent Claim
18 words
A method according to claim 1, wherein the three spaced areas are substantially equidistant from each lens respectively.
Claim 6
Dependent Claim
17 words
A method according to claim 1, wherein the three different colors are red, green and blue respectively.
Claim 7
Dependent Claim
16 words
A method according to claim 1, wherein each photosensor is a two-dimensional array of photosensitive elements.
Claim 8
Independent Claim
87 words
A method of forming a color electronic image corresponding to a light image, comprising: arranging a plurality of lenses so that each individual lens diffractively forms a plurality of substantially identical segments of the light image in a plurality of different colors on a plurality of spaced areas respectively; arranging a plurality of photosensors on said surface at said plurality of spaced areas for receiving the three segments to generate electrical signals corresponding to the segments respectively; and processing said electrical signals to produce said electronic image.
Claim 9
Independent Claim
87 words
A method of forming a color electronic image corresponding to a light image, comprising: arranging a plurality of lenses so that each individual lens diffractively forms a plurality of substantially identical segments of the light image in a plurality of different colors on a plurality of spaced areas respectively; arranging a plurality of photosensors on said surface at said plurality of spaced areas for receiving the three segments to generate electrical signals corresponding to the segments respectively; and processing said electrical signals to produce said electronic image.
