A New Method for the Measurement of Dynamic Angular Errors of a Photoelectric Shaft Encoder
A new method for measurement of dynamic angular error of photoelectric shaft encoder using trigger photoelectric collimator is proposed. The photoelectric shaft encoder rotates at an invariable or variable speed less than forty degrees per second. The dynamic angular error is measured. The standard uncertainty of this method is less than 0.5 arc second.
