| Abstract: | To obtain precise count unit,the method of electronic multiplication and interpolation of Moiré stripe using microcontroller is discussed;The loss of position data at power-down is a disadvantage of incremental encoder,but the problem can be resolved if the system can be re-initialized on power up by searching for the index and re-setting the position counters.The engineering problem of reference mark (index)of incremental optical encoder is also encoder is also discussed and a resolution is offered. |
