Abstract

Multi-degree of freedom for dynamic target vibration measurement problem is widely studied.Established vibration measurement system of dynamic target is based on double area array CCDs.Two cameras are used to capture vibration images of the target.By image processing,the target pixel position information is extracted.According to the target pixel position changes in the whole process,the displacement variation in three dimensions is calculated.Experimental results show that the measuring accuracy is about 0.1mm.Measurement system has the features of compact,high accuracy and applicability.

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
