Abstract

PURPOSE: To obtain a transducer of superior performance and volume productivity by providing a photo detector whose output signals assume a relation of square root, responding the displacements of a light image on the photosensitive face of the photo detector to the displacements that a converting part gives and producing the signals proportional to the rates and velocities of flow.
