The invention relates to a photoelectric encoder suitable for various motors, in particular high-speed and high-precision motors, and supports 32 million lines and 600,000 rpm. The photoelectric encoder is divided into a passive optical coding component mounted on a rotor, a light source + photoelectric conversion + a data acquisition processing module mounted on a stator. The encoder supports absolute and incremental encoding. The passive optical components of different specifications are manufactured through mass production or precision machining in the form of matryoshka dolls by using integrated circuits or micro-electromechanical and precision mold processes. Higher speeds and resolutions are supported as the manufacturing processes are improved. The encoder uses a microlens array toincrease sensitivity, and uses the microlens array to form a spot of a special pattern, thereby increasing a tolerance threshold and facilitating to install and use. The performance indicators of thelight source, a photosensor, a lens array, the passive optical coding component, etc. used by the encoder are related to coding accuracy, the speed, and device size.
