| Abstract: | Fourier technique for measuring the focal length of lens is described. The focalg length of lens is calculated by measuring the distribution of Fouirer transform power spectrum. In the paper, the measurement principle is throretically analyzed, focal length calculation formulas are derived and experimental results are given.The detecting method for power spectrum distribution is discussed. |
