线光源 meaning in Chinese
line source
Examples
- On straight light and reflect light of linear light source
关于线光源的直射光与反射光的研究 - Design of linear light source composed of light - emitting diode array in large light - screen target
大靶面光幕靶中发光二极管阵列线光源的设计 - Through the methods of reflection refraction and accumulation the light could be well - proportioned to be the best way of transmission from light - line to light face
通过对光的反射、折射和累加达到均匀的平面发光效果，用最快捷的办法实现线光源到面光源的转变。 - By means of the rectangular d iaphragm and two orthogonal cylinder lens , the collimated laser is shaped , which is stretched and compressed respectively in two different directions , and the l ine source with ideal shape is achieved
并应用矩形光阑和两个相互垂直放置的柱面镜，对准直后的激光束进行整形，分别在不同的方向进行拉伸和压缩，得到了形状理想的线光源。 - 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。
