4-3. Optical encoders are classified into two types depending on the format of the output electrical signal. Easy development due to relatively simple optical path. When a code wheel attached to a rotating shaft such as a motor rotates, an optical pulse is generated depending on whether light emitted from a fixed light emitting element passes through a slit of the code wheel or not. Reflective optical encoder can be easily miniaturized and thinned. The resolution of an optical encoder is basically determined by the number of slits in the code wheel. Light emitting devices used in optical encoders are generally inexpensive infrared LEDs, but colored LEDs with shorter wavelengths are sometimes used to suppress light diffusion.

In addition, since it is not affected by the surrounding magnetic field, it can be used in applications where a strong magnetic field is generated. The light emitted from the LED is diffused light with little directivity, so that it is made parallel by using a convex lens. In addition, expensive laser diodes are used in applications that require high performance and high resolution. and reducing the distortion of the pseudo sine wave.
