摘　　要：根据数学形态学的基本思想，采用离焦的卷积光学系统，利用电子俘获材料的饱和特性和图像减法功能实现图像微分。这一种方案具有清晰度高、实时性、全并行性的优点。Based on the concept of mathimatical morphology, the real time image differentiation taking use of the saturate property and image subtraction ability of electron trapping materials is performed by using a defocused convolver. This method shows many attractive advanteges such as high resolution, real time parallelism and incoherence. The thresholding and subtraction are performed by a single ET device.
