雷射光本身的高同調特性會使雷射影像檢測系統所接收到的影像產生雷射光斑現象。此現象無疑降低了影像品質，影響觀察者觀看事物時的清晰度和自然性。現行對於雷射影像檢測系統的影像品質優劣判斷，大多利用人因實驗概括表示。
因此，本論文提出一種雷射光斑尺寸與影像解析度間的數學量化模型。此套數學模型能夠量化使用不同抑制雷射光斑現象方法的影像檢測系統所形成的雷射光斑尺寸。以新式發明專利技術取代既有雷射影像檢測系統的照明光源，計算該系統於檢測器上所形成的雷射光斑尺寸。最終模擬不同抑制雷射光斑方法的影像檢測系統，並提出降低雷射光斑尺寸會使檢測器的影像解析度提升與影像檢測系統的檢測距離增加。

The high coherence characteristics of the laser light itself cause a laser speckle phenomenon in the image received by the laser range-gated system. This phenomenon undoubtedly reduces the image quality and affects the sharpness and naturalness when the observer viewing things.
Therefore, this dissertation proposes a mathematical quantitative model between laser speckle size and image resolution. This mathematical model is capable of quantifying the size of the laser speckle formed by a laser range-gated system using different methods of suppressing laser speckle phenomena. The new invention patent technology replaces the illumination source of the existing laser range-gated system. Calculated laser range-gated system, the size of the laser speckle formed on the detector. Finally, the different methods of suppressing laser speckle is simulated by a laser range-gated system. It is proposed that reducing the size of the laser speckle will increase the image resolution of the detector and the detection distance of the laser range-gated system.
