The invention relates to multiple anti-counterfeit watermark paper and a manufacturing method thereof. The watermark paper is provided with patterns, figures or lines which are woven or embroidered by non-water-soluble fibers or anti-counterfeit fibers; and the paper has rich levels and a concavo-convex touch feel under transmission light. A film, non-woven fabric or woven fabric made from a water-soluble material or a hot-melting material is used as a carrier, so that the patterns, the figures or the lines are woven or embroidered on the carrier by using the non-water-soluble fibers or the anti-counterfeit fibers; and the carrier with the patterns, the figures or the lines is released in front of a paper machine net through a positioning and releasing device so that the carrier is combined with paper. Compared with the conventional watermark, the patterns, the figures or the lines of the watermark paper are more fine and smooth; meanwhile, during processing of the patterns, the anti-counterfeit fiber loaded with one or more pieces of anti-counterfeit information (such as fluorescence, color, temperature variation, photoluminescence, magnetism and the like) is adopted; therefore, the watermark is integrated with vision, touch and multiple anti-counterfeit effects of the anti-counterfeit material as well as combination of the vision, the touch and the multiple anti-counterfeit effects.

The present invention discloses a differential phase contrast microscope imaging method based on half-ring-shaped LED lighting. Firstly weak object approximation is used, and an optical transfer function expression of a weak object in a partial coherent illumination imaging system is deduced. A phase transfer function of differential phase contrast imaging in half-ring-shaped illumination is calculated. Two ring-shaped illumination patterns in different directions are orderly displayed on an LED array, and a synchronous triggering signal is generated and sent to a camera. The ring-shaped illumination pattern changes are changed, a synchronous triggering signal is generated and sent to the camera, in triggering signals corresponding to the ring-shaped illumination patterns in different directions, the camera collects a series of intensity images. Differential phase contrast images in different directions can be calculated by a differential phase contrast imaging calculation formula, and thus the differential phase contrast imaging can be realized in up, down, left and right directions and all different directions. According to the method, the low frequency of a low phase in a differential phase contrast image can be improved, thus the concave and convex sense of the differential phase contrast image is strong, and the imaging quality of the image is enhanced.
