Paper Abstract

This paper introduces an easy way to measure melamine. Exploiting the near infrared spectral reflective characteristic of melamine, irradiating the samples with broad spectrum light and the reflected beam goes to the appropriate optical system and optical collimation lens through the optical fibre transmission. Then select a 500nm and a 1000nm wavelengths. The light intensity of the 1000nm wavelength basically does not change as the denseness of melamine changes, while the light intensity of the 500nm wavelength does. According to this feature, people can use the electro optical technology which can turn optical signal into electrical signal to calculate the circuit voltage difference, and then input it into the computer to determine the concentration of melamine in milk. This method is time-saving and convenient.
