Photothermal spectroscopy
Hello, last week I was assigned to do research on the method that was used to measure the glucose level in the blood (non-invasive). This method is called (Photothermal Spectroscopy). Photothermal spectroscopy is a high sensitivity of detecting the changes in the spectra that are produced from the emission of the electromagnetic radiation of the matter. the basics of these techniques are measuring the absorbance of the radiations that were caused by the thermal characteristics of a sample. the changes in the thermal characters are caused by the light that is directed to the sample. When there is no loss of light by the emission, the temperature of the sample will rise therefore it will affect the thermodynamic properties of the sample. Measurement of the temperature, pressure, or density changes that occur due to optical absorption is ultimately the basis for the photothermal spectroscopic measurements. photothermal spectroscopy is an indirect method for measuring optical ab
