激励光 meaning in English
activating light
exciting light
Examples
- Moreover , higher sensitivity can be achieved when a top - hat beam is used as the excitation source
且使用平顶光束作为激励光可以提高光学薄膜微弱吸收的测量精度。 - Numerical results show that the top - hat beam stl instrument is more sensitive than the gaussian beam stl instrument , with a maximum sensitivity enhancement factor of approximately 2 . 3
测量了信号的衍射分布,信号与激励光功率、激励光斑半径、调制频率、探测距离的关系,与理论吻合较好。 - In this paper , the stl technique with cw modulated top - hat beam excitation is investigated theoretically and experimentally . 1 . the theoretical model based on the fresnel diffraction integral is developed to describe the stl signal excited with the cw modulated top - hat beam for the first time to the best of our knowledge
本论文提出采用连续调制的平顶光束作为激励光的表面热透镜技术测量薄膜吸收的方法,主要开展了如下工作: 1 .建立了连续调制的平顶光束作用下样品的表面热透镜信号模型。 - In former stl instruments , a laser beam with a gaussian distributed intensity was commonly used as the excitation source . nevertheless , the output of a high power laser is usually a superposition of multi - modes rather than a gaussian distribution ( tem00 ) . therefore , it is very convenient to add an aperture to get a top - hat beam
以前的表面热透镜装置中,多使用高斯光束作为激励光,但由于高功率激光器一般为多模输出,要获得严格的基模高斯光束比较困难,而平顶光束可以通过在激光器前加一定大小的光阑实现,降低了对激光光束质量的要求,更有利于实际的测量。
