【Abstract】 This paper discussess the relationship among the shape, size of the solidified photopolymer and the Power density, through the theoretical analysis of exposure and solidification by Gaussian beam. By the experiments of solidification with the UV optical fiber directly, two eigenvalues for UV photopolymer solidification, critical solidification energy and absorption coefficient were calculated. Eventually, by computation modeling with MATLAB and solidifying experiments, the theoretical analysis was proved. A useful theoretical foundation has made accordingly for the planar solidification and the stereo photo lithography.更多还原
