POLYMER PLANAR OPTICAL CIRCUIT TYPE DISSOLVED OXYGEN SENSOR

摘要

Provided is a polymer planar optical circuit type dissolved oxygen sensor and a method of fabricating the sensor, including a polymer planar sheet embedded with a first wavelength optical signal transmission line transmitting a first wavelength optical signal emitted from a first optical source and a second wavelength optical signal transmission line transmitting a second optical signal emitted from a sensing membrane and having a fluorescent property, and the sensing membrane coated on the polymer planar sheet, and further including a second optical source emitting the second wavelength optical signal to compare an optical property of the second wavelength optical signal to an optical property of the first wavelength optical signal emitted from the first optical source.
