- W4377004039 abstract "Designing a wide-angle eyepiece’s optical system is a multidimensional problem that cannot currently be solved analytically. The final solution should meet specific requirements on the distortion properties, as well as different user-defined restrictions: overall dimensions, lateral color, etc. To solve this problem, we propose to apply one of the global optimization algorithms, which excludes the necessity of having initial solutions with good image quality. In this work, we carry out parametric aberration synthesis of a series of wide-angle eyepieces with a different number of lenses for use in telescopes or microscopes. All optical systems provide the 90-degree angular field of view, the 17.9× magnification, the 4-mm exit pupil diameter, and the 16-mm eye relief. The parametric synthesis process itself was carried out in an automated mode with the global optimization algorithm based on modified differential evolution. This algorithm was implemented and examined earlier in software PODIL intended for optical systems design. The computer simulations showed that the time interval necessary for automated designing such eyepieces (with a total number of unknown variables up to 60) is about 20 hours. The evaluated aberrations and image quality functions confirmed the high image quality of the designed optical systems of the developed wide-angle eyepieces. The user-defined technical requirements and restrictions set in the merit function are completely met in found solutions. All developed optical systems are well corrected on theta distortion: its value does not exceed 0.6% over the whole field. Future research can be directed onto testing automated design capabilities for other types of optical systems with extreme performances." @default.
