碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 96 === By taking the lens of web camera inside the note book and cellular phone for the example, the topic of this thesis is primarily discussed; and considered of the factors like the manufacturing shape of lens, the shrink ratio of material and the injection molding, we can provide that the compensation against the measurement error of aspheric plastic lens under the method of the cored non-linear compensation. The consequence of this test can reach the improvement during 53.4 to 95.6 percentages after the non-linear compensation. To have better compensated precision mainly on lens curvature and the lens, which the thickness is unsure, the improvement ratio can be during from 43.9 to 92.2 percentages if we fix the shrinking ratio.
