Abstract
Official abstract text for this publication.
A forward looking light sensor is described herein. The sensor includes a first light blocking material; a second light blocking material; and a light sensor with a first surface and a second surface. The first light blocking material is disposed on the first surface of the light sensor and the second light blocking material is disposed on the first surface of the light sensor, and the first light blocking material and the second light blocking forming an aperture.
First claim
Opening claim text (preview).
I claim: 1. A method for implementing a forward-looking light sensor, the method comprising: providing a first light blocking material, a second light blocking material; and a light sensor with a first surface and a second surface; disposing the first light blocking material on the first surface of the light sensor and the second light blocking material is disposed on the first surface of the light sensor, and forming an aperture of value r with the first light blocking material and the second light blocking material forming an aperture, wherein the aperture formed is circular, and sizing the first light blocking material and the second light blocking material with a thickness of value d that extends away from the first surface and the second surface, solving a function to determine an optimal value of d and r, wherein the function is related to an area of the aperture and an angle of incident light being detected by the light sensor, wherein the normalized version of the function is: A o = 1 - 2 π sin - 1 ( d tan θ 2 r ) - d π r 2 tan θ r 2 - ( d tan θ 2 ) 2 , wherein A 0 is an overlap area of the first light blocking material with the second light blocking material, and θ is an angle of incident light.
