Abstract : The patent is directed to an electro-optical sensor which can accurately measure small displacements. The sensor uses a modulated light source and has a shutter whose displacement controls the light which impinges on a pair of phototransistors. The phototransistors are connected to a transformer and their output is a measure of the displacement of the shutter.
