Gratings & Coders

Gratings, coders and modulators play important roles in digital displays, digital controls, photoelectric integration, and other coordinate measure systems. Incremental circular gratings, absolute coders, and modulators have been widely used in the field of photoelectric translating systems, including angle displacement sensors and line displacement sensors.Single loop absolute codersare widely used in total stations and electronic theodolite systems. We have successfully overcome the instability error caused by laser length measuring and have reached an accuracy of±0.1µm in applicationssuch as the variable-transmission MTF sinusoidal grating, the variable-frequency OTF optical transfer function grating, and the novel wavelength grating which uses the wavelengths of Helium and Neon as its raster unit.
