laser line meaning in Chinese
激光线
Examples
- Laser line projector model
激光标线器型号 - The components and application of the 3d laser line scanning system based on machine vision
基于机器视觉三维激光线扫描系统的组成及应用 - Precision target sighting - bright laser line for quick and easy aim and shoot performance
目标锁定精确无误红光明亮,能够准确对准目标并扫描 - 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
在分析点光源激励声表面波机理的基础上,求出了线光源激励的超声振动的位移表达式,发现线光源激励的近场区表面波具有波形好,信噪比高,指向性好,幅度强等特点。通过理论推导,得出共焦fabry - perot干涉仪的输出光强除了与样品表面的振动速度成正比,并与入射角和散射角有关;适当减小cfpi的带宽,增加腔长,增大镜面反射率,或者减小检测入射角都可以提高系统的信噪比。
