Paper Abstract

This paper presents a near-infrared spectroscopy method for measuring milk constituents based on AOTF technique. Some key problems encountered during study of spectrum stability, such as lower stability, parallel moving of the spectrum, were analyzed from the point of view of the system structure and the AOTF driver, The reliability designs, such as heat design, EMC design, and software allowance design, were performed. The capacities against interference and spectrum stability ofthe system have been improved accordingly, the coefficient of variation ofrepeatability within short time-scale has reached to 0.0002, and stability within long time-scale has reached to 0.001.
