OPTICAL DISPLACEMENT TRANSMITTER Russian patent published in 1995 - IPC

Abstract RU 2044264 C1

FIELD: contactless measurement of longitudinal displacements in 0-1000-mm range. SUBSTANCE: radiation receiver in the transmitter is installed in the focus of a collecting lens, four light diodes are positioned, correspondingly, in the focus of one of four collecting lenses so that their optical axes are set at an angle of α to the optical axis of a photodetector and converge in the direction of the reflector; the diffusion reflecting surface is positioned on a moving object. EFFECT: wider measuring range and higher accuracy of measurements.
