摘要
提出一种测量物体固有频率的新方法———旋转剪切频闪散斑干涉法。该方法能方便地测量振动物体的固有频率,具有较高的精度、全场显示、条纹可见度好等优点,给出了理论分析和实验结果。
A new experimental method for measuring resonant frequencies of objects is proposed by use of rotating shearing stroboscopic speckle interferometry. It can easily measure the resonant frequencies of objects with this method. In addition to the advantages of high precision , abetter visibility of lines is provided. The theoretical analysis and experimental result are given.
