| Abstract: | The accurate and quick fringes counting is very important in optical measurement system. Because the many advantages about CPLD, it has brought some new innovations to circuit design. It also gives a better choice to signal processing in the scope of photoelectric measurement. This paper has used the CPLD technology to design the counting circuit in optical measurement system which measures distance by taking count of interference fringe. This design has been proved by our experiment and also can be used in general optical measurement systems. |
