LED spa light device

A method for real-timely monitoring thickness change of a coating film is disclosed. In the method, a coating module having a chamber and a film thickness-monitoring module containing an SPR optical fiber sensor, a light source, a light-receiving detector, and optical fibers are first provided. The optical fibers are used to connect the SPR optical fiber sensor with the light source and the light-receiving detector. The SPR optical fiber sensor has a sensing area and is arranged in the chamber. The light source provides the SPR optical fiber sensor with light. Then, a substrate is put into the chamber. While coating process is performed on the substrate, a film is also formed on the sensing area of the SPR optical fiber sensor. The light-receiving detector receives signals output from the sensing area of the SPR optical fiber sensor and then outputs signals of light-intensity change.

A surface plasmon resonance sensing device that is portable, and having the fiber sensing unit whose resonant wavelength being within the transmission range of a single-mode fiber or a multi-mode fiber, is disclosed. The disclosed sensing device comprises: a light source unit, a fiber sensing unit, an optical sensor, a plurality of fibers, and a computing and displaying unit. The fiber sensing unit includes a trench, a cladding layer, a core layer, a first metallic layer, and a plurality of dielectric thin film layers, wherein the first metallic layer covers the trench, and the plurality of dielectric thin film layers forms on the first metallic layer. The light source provided by the light source unit will become a light signal, after the light passes through the fiber sensing unit. The optical sensor transforms the light signal into a corresponding electric signal, for the usage of the computing and displaying unit.
