Abstract
A fiber-optic apparatus has a multi-mirror optical sensor having an optical source side and an air source side opposite the light source side. The multi-mirror optical sensor has a single-mode optical fiber connected to an optical source and a photodetector on the optical source side and connected to a hollow tube forming a first Fabry-Perot Interferometer on the air source side. The core of the single-mode optical fiber and the air cavity of the first Fabry-Perot Interferometer form a first mirror for reflecting optical light from the optical source. The air source side of the hollow tube is connected to a side-hole optical fiber forming a second Fabry-Perot Interferometer, the side-hole optical fiber has at least two hollow cavity holes symmetrically positioned around the core of the side-hole optical fiber and running longitudinally the length of the side-hole optical fiber. The air cavity of the first Fabry-Perot Interferometer to the optical fiber core of the side-hole optical fiber forms a second mirror for reflecting optical light from the optical source. The at least two hollow cavity holes of the side-hole optical fiber provide an air flow channel to the air cavity of the hollow tube from the air source side of the multi-mirror optical sensor. The end of the optical fiber core of the side-hole optical fiber at the air source side forms a third mirror for reflecting optical light from the optical source.
