Physicists solved the 2000-year-old optics problem 2 октября, 2021


Physicists have developed a method for forming aspherical surfaces of optical lenses, which allows you to completely eliminate the problem of blur image at the edges.

More than 2,000 years ago, the Greek scholar Diocl found this undesirable effect and suggested that the distortion occurs due to the change in the angle of the fall of light on the spherical lens, as a result of which it does not focus. After developing analytical tools for describing the problem in the twentieth century, researchers and engineers came up with various ways to solve it for specific devices and tools. Although the previous decisions to change the refraction were, based mainly on aspherical lenses, helped, but were expensive but were not universal.

Recently, three physicists from the National Autonomous University of Mexico and the Monterrey Technological Institute proposed solving problems with lenses. It consists in describing the method of forming aspheric surfaces of lenses, taking into account the distance between the object and the image. In essence, it is based on the fact that the second surface corrects the problems of the first, eliminating its spherical abberation.

After creating a long mathematical formula, the team checked it. The simulations have shown that the proposed solution will make it possible to produce lenses with an accuracy of 99,999999999% for various devices, including glasses, contact lenses, telescopes and microscopes.

Recall that earlier engineers developed a camera that is able to remove objects on
