| Popis: | The previously proposed method for noninvasively measuring the positions of elements in the human eye is further developed. A procedure for increasing the resolution of the method based on decreasing the discreteness of measurements is proposed and implemented in numerical experiments. For a system of two closely located phase screens, the resolution was increased 16-fold, which made it possible to determine the positions of the two screens. In order to resolve the positions of all optical elements, for the Gullstrand eye model, it was sufficient to increase the resolution and the Fourier filtration by a factor of four. |
