The conclusions are as follows : the ultrasonic intensity is proportion to the laser intensity ; the ultrasonic induced by a laser line source has much more advantages than by a laser point source, such as stronger energy, higher snr, more directivity and shape ; the intensity of cfpi ' s output signal is linear with ultrasonic vibration velocity, and is effected by incidence angle and scattered angle ; snr will increase by reducing cfpi ' s bandwidth, reducing incidence angle, increasing cavity ' s length and reflectivity
在分析點光源激勵聲表面波機理的基礎上,求出了線光源激勵的超聲振動的位移表達式,發現線光源激勵的近場區表面波具有波形好,信噪比高,指向性好,幅度強等特點。通過理論推導,得出共焦fabry - perot干涉儀的輸出光強除了與樣品表面的振動速度成正比,並與入射角和散射角有關;適當減小cfpi的帶寬,增加腔長,增大鏡面反射率,或者減小檢測入射角都可以提高系統的信噪比。
