Patent ID: 7161129

Claim:
A method of determining a location of each of a plurality of optical components with respect to a plurality of pixels comprised by an array, the method comprising: providing the array of pixels, wherein the array is generally planar and wherein the pixels are arranged in columns and rows having a pitch; providing a focusing lens having an optical axis normal to the array; and placing each of the plurality of optical components in relation to the optical axis and an associated pixel, wherein the optical components are grouped into matrices of adjacent optical components, wherein each matrix of optical components includes a first group having one or more of the optical components and a second group having one or more of the optical components, wherein the optical components have a dimension parallel to a plane defined by the array, wherein the dimension for the first group is a first value, wherein the dimension for the second group is a second value, and wherein the first and second values are different; wherein a first portion of the plurality of optical components comprise microlenses and wherein placing each of the plurality of optical components in relation to the optical axis and an associated pixel includes determining a location of each of the microlenses with respect to a location of one or more optical obstructions within its associated pixel.
