Distance measurement with the low coherent interferometer with silver mirror (the source wavelegth 1310 nm) - 40 um (serie 1)

Description

The obtained data was acquired by the interferometric fiber-optic sensor of distance. The setup was constructed of a broadband light source working at the central wavelength of 1310 nm, an optical spectrum analyzer, and a fiber-optic 2x1 coupler (with the power split 50:50). All elements were connected by standard single-mode optical fibers. The measurement head was made by a polished fiber end-face and an external mirror placed parallel to the fiber, creating a Fabry-Perot cavity. The silver film played the role of the mirror. The cavity length was changed by the use of a micrometer screw. Air was fulfilling the cavity during the whole experiment.

Measurements of distance were performed in the range of 0 – 200 µm with a step of 10 µm.

In the first column, there is the value of the wavelength [nm].

In the second column, there is the value of the power density [W].
