【Abstract】 The anthers have developed a transmission point array grating named "Photocolor Plate" in an area of 13×13 cm~2 on the surface of the PMMA. It shapes as a precise square array of micro pyramids with a density of 360000 units cm. It can disperse a beam of white light in colorful images in different directions. This characteristic may make it as a new decorate material in future.更多还原
