A positioning device comprising a motor, a driver for driving the motor, and a digital signal processor for performing an operation for positioning control for the motor.
摘要:
There are disclosed a signal processing method, and a displacement information measuring apparatus utilizing such method, capable of providing highly reliable binary signals even in the presence of a time-dependent variation in the light emission intensity of the light source, a variation in the emission intensity resulting from a variation in the external temperature, or a variation in the optical transmittance resulting from smear on the optical scales, thereby enabling highly precise detection of the displacement information of the movable member.
