Abstract

Traditional near-infrared spectrum analyzer need to be operated in assistant of PC, therefore, they are usual expensive and larger size. Here a portable near-infrared spectrum analyzer based on ARM-Linux was designed to accelerate the process of measurement automation. The measurement setup was composed of light source, optical beam splitting system, detector, data acquisition board, signal processing system, ARM controller module and corresponding embedded software system. To improve the measurement accuracy by suppressing noises and accumulating signals, the lock-in amplifier technology was applied in data processing. The characterization evaluation proved that the analyzer is ideal in practice for its intelligence, convenient and stability and repeatability.
