Scanning means is also known as produced when angle or circular motion when code-disc is rotated on optical-electric module, measurement encoder
Apart from length, electric energy is converted into by luminous energy and exported, output signal shows the information of rotor starting point.
This optical-electric module is usually used on the encoder, and encoder is used for the motion for measuring rotor, accurately determines
The only corner of the angle second of very little.Because in Application Optics measuring principle, the accurate measurement result of base, therefore this can be reached
The encoder of sample is usually mounted with optical measuring system.Mostly using the code-disc of printing opacity, scale, its scale are provided with the code-disc
In circumference uniform distribution, it is divided into different angles to determine the precision of work.In order to ensure accurate measurement result, it is necessary to accurately solid
Determine on the encoder.In the prior art, grating and light-sensitive element become one, it is impossible to which adapting to smaller or greater angle needs
Ask.
