Abstract
The accuracy of an optical position sensor that detects the peak of the incident light depends on the resolution of its pixel pitch. However, an accuracy limit is reached where the pixel pitch can not be designed smaller. In this paper we describe a novel idea using skewed pixel arrays to improve the resolution of the position sensor and simulation results of using three algorithms for calculating the peak of the incident light show the effectiveness of this design and the optimized numbers of skewed rows needed according to different incident light conditions.
