Abstract: A pixel array system for high accuracy detection of displacement, speed or acceleration includes: an array including a plurality of pixels, each pixel touching at least one other pixel in a same row and touching at least one other pixel in a different row. At least one row is offset with respect to a preceding row of the array by less than 50% of a pixel width. The array receives an input from an object passing over at least the offset row and the preceding row, and detects displacement, speed or acceleration of the object when said object passes over the array, in order to generate an output representing at least one of the detected displacement, speed or acceleration of the object.
