  1. By using knife edge as object, and cmos sensor as device for image analyzing, we get edge spread function from the image and use differential operation and fft to obtain modulation transfer function of the lens, then its image quality is known

    以刀口作為目標物，以cmos作為圖像分析器件，從圖像中獲取刀口函數，經微分和fft運算，得到成像鏡頭的mtf （調制傳遞函數） ，從而得知其成像品質。
  2. Experiments show that the algorithm presented in this paper is able to effectively overcome bluring affects caused by the point spread function and apparently promote the recognition rate, and the algorithm is better than that based on edge detection

    實驗結果表明，這里提出的演算法能有效克服光學系統的降晰對條碼識別的影響，顯著提高了識別率，其性能優于基於邊緣檢測的演算法。
  3. The system is on the basis of fourier optics. by using knife edge as object, cmos sensor as device for image reception, we get edge spread function from the image histogram and use differential operation and fft to achieve mtf of the lens, then its image quality is obtained

    本系統以傅立葉光學為依據，以刀口為目標物，以cmos為圖像接收器件，採用獨特的演算法，從刀口圖像的灰度直方圖中獲得其刀口邊緣函數，經微分和fft運算，得到待測鏡頭的mtf ，從而得知其成像品質。
