Abstract
Дифференциальный поляризационный интерферометр, включающий оптически связанные источник когерентного, перестраиваемого по частоте излучения и первый поляризатор, отличающийся тем, что содержит широкополосный неполяризующий куб-светоделитель, формирующий две оптически связанные ветви, в первой ветви последовательно расположены двоякопреломляющий элемент, установленный на основании с регулировкой поворота, образец, состоящий из прозрачной подложки, на часть поверхности которой нанесена исследуемая пленка, установленный на основании с регулировкой сдвига положения и наклона, прерыватель оптического излучения с системой отверстий, плоское широкополосное зеркало, отражающее падающие на него пучки в обратном направлении и обеспечивающее двукратное прохождение излучения через образец и двоякопреломляющий элемент, во второй ветви интерферометра последовательно расположены управляемый фазовый компенсатор, второй поляризатор и фотоприемник.A differential polarization interferometer, including an optically coupled source of coherent, frequency-tunable radiation and a first polarizer, characterized in that it contains a broadband non-polarizing cube-beam splitter that forms two optically coupled branches, a birefringent element located in series on the base with rotation control a sample consisting of a transparent substrate, on the part of the surface of which the investigated film is deposited, mounted on the basis of with adjustment of the position and tilt shift, an optical radiation chopper with a system of holes, a flat broadband mirror reflecting incident beams on it in the opposite direction and providing double transmission of radiation through the sample and the birefringent element, in the second branch of the interferometer there is a series-controlled phase compensator, a second polarizer and photodetector.
