| Abstract | A point light source angular position-detecting system with wide operating range and high resolution is developed. The sensing part consists of a simple mask with multiple pinholes to cast multiple images of a point light source onto a single CCD area image sensor. The 2D angular position of the light source is computed from results of curve-fitting through the image positions. The computational burden is low, yet an unusually wide operating angle at high resolution throughout is achieved with a single image sensor |
