  1. For example, the geometric effect and vignetting are simulated with the synthetic method in which they are modeled with ray tracing and then simulated with pixel - based processing. the effects of detector noise on imaging are simulated with the three - dimension model. the theory of pixel transfer function is extended and developed, and microscanned images of four patterns are simulated with good results

    本文具有如下幾個突出特點:用光線追跡法分析建模,而用基於象素處理的綜合方法,模擬了光學系統中的幾何效應和漸暈現象;利用三維噪聲模型,模擬了探測器噪聲對圖像質量的影響;對象素傳遞函數理論進行了擴展和延伸,給出四種工作模式的微掃描成像系統的象素傳遞函數的具體數學表達式,並利用這些表達式模擬了探測器的空間效應和微掃描成像的圖像效果。
  2. The gauss - ray tracing have the dynamic and geometric character. it can compose the record by calculating the high frequency wave in transverse anisotropic medium, avoiding getting the accurate ray path. it is a very steady and effective method with little calculation time and a good precision

    高斯射線束正演包括地震波運動學特徵和動力學特徵,能有效的計算橫向上不均勻介質中高頻體波的合成紀錄,避開了精確求取兩點射線路徑,大大減少了計算的時間,同時又具有較高的精度,是一個很穩健有效的方法。
