  1. We also derived the relationship between the radial local density distribution and the observed line integral density distribution by fourier integral transform. on this basis, the density inversion calculation is realized through fft method and is independent of abel inversion

    另外，本文還著重推導了線積分密度分佈和徑向體密度分佈之間的傅立葉積分變換關系，並利用快速傅立葉變換實現了完全拋開abel反演公式的密度反演計算。
  2. 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。
