Abstract

In this paper, to find the quantitative errors of aqueous glucose induced by the temperature change at every wave point ranging from 1200 to 1700 nm, the calibration curve is calculated and shown. During the measurement the temperature varies from 30°C to 40°C, at a 2°C interval, and aqueous glucose concentration ranges from 100 mg/dL to 500 mg/dL, at a interval of 100 mg/dL. The absorption of aqueous glucose decreases with the increasing of temperature, also the absorbance decreases. In addition, only 1°C change in the temperature induces about -7xlO^-3and -4x10^-3 errors in the absorbance of the aqueous glucose at the wavelength of 1550 and 1610 nm respectively. To decrease or even eliminate the error caused by the temperature, two methods are put up in this paper.
