اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولSpherical Aberration of Intraocular Lenses
Advancements in cataract surgery and intraocular lens (IOL) design have optimized the postoperative optical performance of the pseudophakic eye. One of the recent spotlights of IOL design has been formulating optical properties similar to a clear, young lens and addressing spherical aberration. Spherical aberration in the human eye is a combination of the positive spherical aberration of the co...
متن کاملIn vitro strehl ratios with spherical, aberration-free, average, and customized spherical aberration-correcting intraocular lenses.
PURPOSE To determine in vitro image qualities of artificial eyes achieved with spherical, aberration-free, average spherical aberration-correcting, and customized spherical aberration-correcting IOLs in centered, decentered, and tilted positions. METHODS The in vitro performance of these IOL models was determined by optical bench measurements. The experimental setup included a laser light sou...
متن کاملSpherical Aberration, Accommodation and Myopia
Myopia should not be considered a benign condition because of the potential risks of vision loss associated not only with high myopia but also with the procedures used to correct myopia. Results from animal studies demonstrating that emmetropization is an active rather than a passive process and the induction of myopic refractive errors with imposed hyperopic defocus underlie the hypothesis tha...
متن کاملWavefront spacing and Gouy phase in presence of primary spherical aberration.
We study the Gouy phase of a scalar wavefield that is focused by a lens suffering from primary spherical aberration. It is found that the Gouy phase has different behaviors at the two sides of the intensity maximum. This results in a systematic increase of the successive wavefront spacings around the diffraction focus. Since all lenses have some amount of spherical aberration, this observation ...
