  1. Abstract : a new method for determining proximity parameters, and in electron - beam lithography is introduced on the assumption that the point exposure spread function is composed of two gaussians. a single line is used as test pattern to determine proximity effect parameters and the normalization approach is adopted in experimental data transaction in order to eliminate the need of measuring exposure clearing dose of the resist. furthermore, the parameters acquired by this method are successfully used for proximity effect correction in electron - beam lithography on the same experimental conditions

    文摘:在電子散射能量沉積為雙高斯分佈的前提下，提出了一種提取電子束光刻中電子散射參數，和的新方法.該方法使用單線條作為測試圖形.為了避免測定光刻膠的顯影閾值，在實驗數據處理中使用歸一化方法.此外，用此方法提取的電子散射參數被成功地用於相同實驗條件下的電子束臨近效應校正
  2. In the paper, both the size of the source and of the beam spot of a extended gaussian beam are considered and their influences on both the lateral and axial resolution of a fluorescent confocal microscopy are studied and calculated based on the power transfer function and three - dimensional pulse spread function

    摘要研究一定光源孔徑、束斑的高斯光束對熒光共焦顯微鏡橫向、縱向解析度的影響，導出了熒光功率傳輸函數、三維響應函數。
  3. Using kalman model and gaussian random phase - screen fft, we simulated the distribution of illumination beam through long distance atmosphere and its frequency character. also other facts in simulation were analysised, such as reflection of niaterial under natural lighting, point spread function of optic system and electronic noise
