  • Interferometric device for encoding shaft angles
    Patent number: 3955083
    Abstract: In a shaft angle encoder, an optical system translates the shaft angular displacement into a difference of two optical path lengths and that difference is measured by interferometry. Light from a monochromatic source is split and both the transmitted and reflected beams are passed along separate paths through an optical component that moves angularly with the shaft and varies the lengths of the separate paths differentially according to the shaft angular displacement. The transmitted and reflected beams are then recombined and the interference fringes in the recombined beam sensed by a detector.
