最后采用了PROM器件作为空间调制器，在实时相干光系统中进行边缘增强效应处理，获得了轮廓清晰的物体图。
Finally, with PROM device as spatial modulator and edge enhanced processing in a real time coherent optical system, a clear image of object can be produced.
当灰度值相近而边缘交错时，边缘增强效应消失，仅靠灰度级的差别区分，分辨能力降低到40／256级灰度以下。
On the contrary, while the rim fuse, the resolution will decrease lower than 40/256 since the rimenhance effect disappear, the distinction totally depends on the grayscale.
