Optical Encoder System
An optical encoder system is a device used for precise measurement of position or speed, and it is widely applied in fields such as industrial automation, machine tools, and semiconductor manufacturing. It detects displacement or position changes by reading precise optical patterns on a scale or disc. The system consists of a readhead and a scale or disc, where the light source and sensor within the readhead detect changes in light waveform from the scale or disc and convert them into electrical signals. The scale typically made of stainless steel or nickel with optical patterns etched on it, providing accurate position information. Ultimately, the signal processing unit converts these electrical signals into precise displacement data. Due to its high resolution and accurate feedback capabilities, optical encoder systems excel in fields that require precise motion control.
