A Study on the Method and Application of Software Dynamic Subdivision of Incremental Encoder

To improve the shutter synchro precision of the synchro cemera,the intereface circuitry of the orignal coder is changed by dynamic subdivided of software,and it is debuged and tested after the control software change which the dimension of coder is converted into unit based on the orignal hardware system.The result of expriment indicates that the synchro time is much shorter and the synchro precision is large improved with the different cemera frequency,after the location information of coder subdivided.The resolving power of coder location is improved,and it is benefit to short the synchro time and improve the synchro precision of the synchro cemera under dynamic subdivided by the increasing coder software,which is based on the original machine-configuration is not changed.
