Abstract
Two and three dimensional position sensing systems and sensors for use in such systems are disclosed. The sensors incorporate linear array sensors and an aperture plate to block light or other radiation from reaching most elements of the sensors. A direction of a radiation source relative is determined based on illuminated sensor elements in each sensor. The sensors are combined in systems to allow the position of a radiation source to be estimated.
