gaussian hat 中文意思是什麼
gaussian hat
解釋
"高斯帽-
The three - dimensional profile of the temperature rise, the radial profile of the surface deformation and the diffraction signal of the probe beam obtained with both top - hat and gaussian beam excitations are compared by numerical calculations
求解對應的熱彈方程,得到表面形變場分佈。 2 .通過數值模擬,比較了平頂光束和高斯光束激勵下樣品內部溫度場、表面形變場和探測光衍射信號的徑向分佈。 -
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
以前的表面熱透鏡裝置中,多使用高斯光束作為激勵光,但由於高功率激光器一般為多模輸出,要獲得嚴格的基模高斯光束比較困難,而平頂光束可以通過在激光器前加一定大小的光闌實現,降低了對激光光束質量的要求,更有利於實際的測量。 -
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
測量了信號的衍射分佈,信號與激勵光功率、激勵光斑半徑、調制頻率、探測距離的關系,與理論吻合較好。 -
The results show that there is gain narrowing when pump is gaussian temporal profile and it ' s pulse width close to signal ' s and that the spectrum extended in the case of saturated amplification when pump is near top - hat temporal profile
在泵浦光為高斯時間波形且脈寬與信號光差不多時,出現增益窄化;而當泵浦光近似為時間平頂時,飽和放大后光譜增寬。
