Study on Digital Speed Measurement for the Optoelectronic System

摘要

First, analog and digital, the two kinds of speed measurement methods are introduced for the optoelectronic system. The realizations, characters, and performance compares of DSMM (digital speed measurement methods) are discussed in detail, then. In specific, the techniques of FD (Frequency Divider) and high-speed pulse interpolation are introduced. These techniques can improve the performance of DSMM too much. At last, the developing prospect of DSMM is put forward for the optoelectronic system.
