A special one-dimensional position-sensitive device for detection of a light-spot location is designed and fabricated. The device is composed of a pair of photodiodes with complementarily interdigited comb configuration. The width of comb teeth is characterized by a designated distributive function, hence, the coordination information of a light spot falling upon the device can be determined by photo-induced currents of the two diodes. This device is useful as the position sensing element in camera-autofocus application.
