Title:
INTERFERENCE MEASURING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2013/141112
Kind Code:
A1
Abstract:
The present invention relates to an interference measuring apparatus, which is provided with a multicore optical fiber having first and second ends, a light source, a light receiver, a splitting section, a joining section, a measuring light path, and a reference light path, and measures a physical quantity of the subject to be measured, said subject being on the measuring light path. The light source and the light receiver are disposed on the side of the first end, and the measuring light path and the reference light path are disposed on the side of the second end. The splitting section splits light transmitted from the light source into measuring light and reference light, and the joining section generates interference light of the measuring light that has propagated through the measuring light path, and the reference light that has propagated through the reference light path. The light receiver detects intensity of the reference light.
