うずまきシャッタを使用したホログラフィ干渉法 (第2報)

変位解析への応用

抄録

In the 1st report, two new devices named a swirl type shutter were designed and applied to the vibration measurements by holographic interferometry, in order to remedy the defect of the realtime method. This paper deals with deformation measurements of object, and describes the feature of the methods comparing with the conventional one. These techniques consist of two, one is used for measurement of deforming amount, and the other for measurement of deforming velocity. The methods of measurement using a swirl type shutter have been studied and are of more practical use compared with the real-time one.
