PROBLEM TO BE SOLVED: To improve the security holding property by adding such a function to a pattern composed of an ensemble of cells of diffraction gratings that the pattern is not visible under normal observation conditions with white light but a real image is reproduced and visible only ...
2. Intensity in the grating diffraction pattern 3. the characteristics of of the pattern 4. Grating Spectrometers(光栅光谱仪) If the grating is illuminated by white light with a continuous distribution of wavelengths, each value of k corresponds to a continuous spectrum in the pattern. The angle...

as is the first layer height. This is because the first layer of plastic has to meld perfectly with the diffraction grating to pick up the pattern. Too high and the grooves won’t transfer to the plastic, and too low, and it’s likely you’ll just melt the grating itself. Setting the...
