Теоретически исследована трансформация профиля однородного монохроматического пучка с плоским фазовым фронтом после прохождения квадратного аподизатора, состоящего из зубчатой диафрагмы и пространственного фильтра, и при распространении за ним. Показаны основные отличия от случая круглой геометрии аподизатора. Рассмотрены роли формы углов квадратной зубчатой диафрагмы, фазы при дифракции Френеля, формы зубцов диафрагмы и отношения ширины зубцов к их высоте.
