From a hardware perspective, the subdivision technology of incremental linear encoders primarily relies on improvements in the precision of code disk manufacturing.

In modern industrial automation systems, the incremental optical encoder, as a core sensor for position and velocity feedback, directly impacts the control accuracy and operational safety of the equipment.

The manufacturing precision of the grating ruler directly determines the resolution. High-precision encoders require the use of a laser interferometer to calibrate the grating spacing to ensure that the error is less than the micrometer level.

Traditional incremental encoders cannot provide absolute position information, while early multi-turn absolute encoders relied on mechanical gear sets to record the number of turns, resulting in defects such as wear, short lifespan, and poor shock resista

In modern automation, robotics, and precision motion control, real-time sensing of rotational position, speed, and direction is crucial for stable system operation.

Deep within the high-speed operation of automated equipment, precise position and speed information is fundamental for the control system to make correct decisions.
