Title:
POLARIZATION DIVERSITY OPTICAL INTERFEROMETER AND MICROSCOPE USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/002720
Kind Code:
A2
Abstract:
The present invention relates to an optical interferometer and a microscope using the same, and the optical interferometer comprises: a light source; a beamsplitter which splits light generated from said light source; a polarization splitter which splits said light into lights having mutually vertical polarized directions; and a plurality of photo detectors which detect said split lights, wherein at least one of said photo detectors is a polarization change detector capable of detecting a polarization change if the emitted light reflected or transmitted on a sample has a polarization diversity. According to the present invention, polarization changes in accordance with samples can be detected such that the invention is applied to all sorts of analysis devices for relevant study or to various equipment, and further optical characteristics of the samples are measured in a more precise manner.
