A Fast Subdividing Circuit Design for Moire Frenge Grating with Smart Materials and Structures

摘要

The key problem for improving the precision of grating sensor is the subdivision technology. According to the instable condition of traditional monostable trigger subdivision circuit works on fast condition, this paper adopts CPLD to judge the logic signal, can identify direction, subdivide and count. In addition, we have introduction of the exterior synchronous clock. The technology not only overcome the instable situation but also improve anti-jamming of circuit system. It has been proved that the method get the better effort in practice.
