Abstract

Vibration is a widespread phenomenon in nature, and vibration detection and analysis of objects can improve the safety of precision equipment. However, real-time performance in the existing laser Doppler interferometry data analysis and processing system remains an ongoing challenge. This paper implements a laser Doppler vibration software based on overlapping frames, according to the data processing method of real-time spectrum analyzer in RF signal measurement and parallel programming method. Under different overlap rates, this paper compares the difference in refresh rate caused by three data processing methods. Experimental results show that the higher the overlap rate, the better the real-time performance of the software. The system can meet the design index of refresh rate(13Hz), has good display fluency and real-time display, and has certain reference significance for related research.
