摘要： Apparatus for detecting displacement of optical image is disclosed which comprises a photosensitive element array, a first circuit, a second circuit and a phase difference measuring circuit. The photosensitive element array is composed of a number of photosensitive elements disposed on and near the focal plane of an image forming optical system through which an optical image is formed. The first circuit multiplies the electric outputs from photosensitive elements in the array by vectors whose phases sequentially increase or decrease, and then adds the products together to form an added output. The second circuit multiplies the electric outputs from photosensitive elements slightly shifted from the above elements in the same array, and then adds the products together to form a second added output. The difference in phase between the first and second added outputs is measured by the phase difference measuring circuit.
