: In the diagnosis of glaucoma, segmentation of optic cup and optic disc based on digital fundus image is a common diagnostic method. In order to segment the cup and disc accurately, we proposed a segmentation method based on the improved U-Net. Compared with the traditional U-Net, a residual block was used to improve the down sampling part, and convolution part was used to improve the skip connection, so that the network could obtain more sufficient feature information. The Dice and IOU of the optic disc segmentation model and the optic cup segmentation model on DRISHTI-GS data set reached 98.3% and 97.2%, 93.2% and 88.5%.

Abstract: In order to achieve the fine analysis and classification of the defects on the panel, the apochromatic objective with a numerical aperture of 0.42 in the visible spectrum and illumination optical system were designed. First, the objective lens was designed with reasonable structure optimization, optical focal length distribution and material selection, and the MTF curve is closed to the diffraction limit. Secondly, the illumination optical system is designed by the scheme of Kohler illumination. Simulating optical system with Lighttools software.The experimental results show that the resolution of the optical system can reach 0.775 μm and the illumination uniformity can reach 98%. The results are consistent with the actual test results and meet the requirements of highprecision panel inspection.
