Energy correction method for multispectral blood glucose photoacoustic detection

The invention provides an energy correction method for multispectral blood glucose photoacoustic detection, which comprises the following steps: taking a certain wavelength as a reference wavelength, taking the output energy of the wavelength and a blood glucose photoacoustic value as an energy base line and a photoacoustic value base line, then obtaining the output energy deviation and the photoacoustic value deviation of other wavelengths, and correcting the output energy deviation and the photoacoustic value deviation of the other wavelengths; the method comprises the following steps of: acquiring an energy deviation correction function of a photoacoustic value, then performing energy correction on the photoacoustic value corresponding to the concentration under each wavelength according to the energy deviation correction function to obtain a relation model between the blood glucose concentration and a new photoacoustic value, and finally establishing a mapping relation expression between the blood glucose
