THE OPTICAL TRANSFER FUNCTION OF CONFOCAL SCANNING LASER MICROSCOPY WITH GAUSS SOURCE
高斯光束共焦扫描激光显微镜的光学传递函数

Taking into account the size effect of the source and the detector, we have calculated the Optical transfer function of a real system with Gaussian distribution of the source. Because of the Gaussian distribution source , the size of source and detector can be enlarged, and the signal-to-noise ratio will be increased.
