5. without making the paraxial approximation, a detailed study on the propagation of ultrashort pulsed bessel beams in linear normal and anomalous dispersive media has been performed using the method of fourier transform
未作近軸近似的條件下，用傅立葉積分變換法詳細研究了超短脈沖貝塞爾光束在正、負色散介質中的傳輸特性。 -
Based on the theoretical expression of the average intensity in the fourier transforming and imaging optical system with variable aperture, an algorithm is developed to change the intensity data versus the aperture radius into the bessel - fourier - transform - and - the - inversion of a function of the height - height correlation function. three samples of gaussian correlation are used for the experimental demonstration
在理論分析和實驗測量中，我們採用了變孔徑的傅立葉變換和成像系統，由所得到的像面光強的解析式，建立了將平均光強隨孔徑的數值變化關系轉化為正逆傅立葉變換對，從而恢復出表面的高度?高度相關函數。 -
7. propagation properties of flattened gaussian, bessel - super - gaussian and laguerre - gaussian beams are studied by using the collins formula in the frequency - domain and hankel transform. the results are compared with those by means of the collins formula in the space - domain, and the advantage of the method is discussed
用頻域collins公式和hankel變換研究了平頂高斯光束、貝塞耳?超高斯光束以及拉蓋爾?高斯光束的傳輸特性，並與空域collins公式計算結果作了比較，同時討論了該方法的優點。
