Abstract
The image of an object is focused on a pair of photoelectric transducer arrays through a focusing lens, a beam splitter, and cylindrical lenses, the photoelectric transducer arrays having longitudinal axes extending substantially perpendicularly to each other. A scanning unit operates to move object images one-dimensionally over the photoelectric transducer arrays at an angle to the longitudinal axes thereof. A control unit is responsive to detected signals from the photoelectric transducer arrays and generates a scanning signal for the scanning unit for determining a two-dimensional position of the object with respect to the photoelectric transducer arrays. The beam splitter and the cylindrical lenses may be dispensed with, and the photoelectric transducer arrays may be replaced with a matrix of four photoelectric transducers.
