Abstract
We introduce a novel approach for measuring glucose concentration through mid-infrared transmission spectroscopy. This method utilizes a high-speed infrared spectroscopic technique employing a mid-infrared wavelength-swept (center wavelength 9.3 μm) pulse quantum cascade laser (QCL). Additionally, a special asynchronous signal control method is developed to reduce the measurement time to 20 ms. With the high power of the QCL and the proposed algorithm, the concentration of glucose solution samples can be accurately measured.
