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。On the design of the system, the thickness measure system of mems chip is built based on lbu and pump - probe technology. on the analysis of data, the reflectivity curve is analyzed using the law of reflectivity change induced by ultrasound, and the thickness is calculated using the system designed by the article, to aluminum film the size of about 20nm can be measured, when the film be measured is single layer, the relative error of the system is less than 2 %, when the film be measured is double layer, the relative error of the system is less than 10 %
