Referring to the existed methods and abundant experiments , a new engineering - oriented technique named single - point phase - detecting vibration - resistant method is presented . it uses piezoelectric transition ( pzt ) as its device for phase compensation to guarantee measure precision 當(dāng)振動(dòng)引起干涉條紋變化時(shí),控制壓電陶瓷( pzt )移相器向相反方向移相來鎖定干涉條紋相位不變,穩(wěn)定干涉圖保證測量精度。
