Описан метод формирования микромеханических элементов для приема вращательного момента (микротурбин) от вихревых световых пучков. Приведены результаты экспериментального изготовления большого количества микротурбин. Приводятся результаты измерения формы микротурбин на оптическом микроскопе, интерферометре белого света ZYGO и электронном микроскопе.
We have considered the simplest lens consisting of refractive and diffractive lenses, in which the shape of the diffractive lens compensates for the main geometric aberrations. We have considered a way to calculate such a system based on minimizing chromatic aberration. We presented the results of an experiment in which the modulation transfer function of a hybrid lens was directly determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
