Peculiarities of the formation of homogenized images by plane-focusing Fresnel lenses
An algorithm for simulating Fresnel microprism concentrator lenses, which forms a homogeneous image of the transmitted light rays in the focal plane, has been developed. Such flat-focusing lenses make it possible to form an optimal signal in systems of automatic control of moving objects with four-p...

A feature of focusing structures created by the diamond cutting technique is a discrete change in the refractive angles of microprismatic zones, resulting in the discreteness of the images formed in the focus. This is a main difference from Fresnel focusing optics with aspherical convex circular surfaces, when the angles of refraction change continuously. In the manufacture of such new devices by the diamond cutting method it is possible to obtain almost mirror working surfaces of a high optical quality.

With the help of collimated «green» laser beam, some samples of specialized transforming microprism structures were experimentally investigated, that form the uniform illumination of a light spot in the form of a light circle and a circle with a ring.

Розроблено алгоритм моделювання мікропризмових концентраторних лінз Френеля, які формують у фокальній площині гомогенне зображення пройдених світлових променів. Такі плоско-фокусуючі лінзи дозволяють формувати оптимальний сигнал у системах автоматичного керування рухомими об’єктами з чотирьохплощинними фотодетекторами, а також є перспективними для використання в сонячних фотоелектричних модулях. За допомогою колімованого лазерного променя експериментально досліджено деякі зразки спеціалізованих трансформуючих мікропризмових структур, які виготовлено методом алмаз-ного мікроточіння за результатами моделювання і формують у фокусі рівномірне освітлення світлової плями у формі світлового кола та кола з кільцем. Методом комп’ютерного моделювання знайдено профілі пройдених світлових променів, що дозволило виявити причини додаткового розширення заломлених потоків світла.
