dc.description.abstractЗдійснено моделювання оптичних властивостей лінзи Френеля з електрокерованим шаром для пристроїв оптоеоектроніки за допомогою програмних пакетів SolidWorks та Zemax. Виконано аналіз неоднорідності розподілу електричного поля в системі акрил – нематичний рідкий кристал. Розроблено метод створення оптичного шару складної форми зі змінним значенням показника заломлення. Показано, що запропонована структура дає змогу створити електрокеровані лінзи із фокусною відстанню, яка змінюється електричним полем у широких межах, із застосуванням шару нематичного рідкого кристала < 100 мкм. Виявлено причини утворення оптичних аберацій та способи їх усунення.
dc.description.abstractThis work is dedicated to the modeling of the optical properties of a Fresnel lens with an electrically controlled layer for optoelectronic devices. The modeling was performed using SolidWorks and Zemax software packages. The analysis of the nonuniform distribution of the electric field in the acrylic – nematic liquid crystal system was conducted. A method was developed for creating an optical layer of a complex shape with a variable refractive index. It is shown that the proposed structure makes it possible to create electrically tunable lenses with a wide range of focal length adjustment via an electric field, using a nematic liquid crystal layer of less than 100 µm. The causes of optical aberrations were identified, along with ways to eliminate them.
