A analogy between optical beating in the inverse transmittance spectrum of transparent double-layer structure and a beating phenomenon known from the standard vibration theory has been considered. We have determined analytical conditions under which the optical beating manifests itself the most clearly in the interference spectra of multilayer structures.

Keywords: multilayer structure, spectral envelopes, optical beating.

Анотація. Представлено аналогію між оптичним биттям в обернених спектрах пропускання прозорої двошарової структури і явищем биття, відомим з теорії коливань. Визначено умови, за яких оптичне биття найчіткіше виявляється в інтерференційних спектрах для багатошарової структури.
