摘　　要：针对在野外环境下快速准确检测人体生化指标的需求,基于MOMEMS和嵌入式技术,设计基于微型光谱仪的微型生化检测仪检测系统。该检测系统包括:光学系统模块,直线型光谱扫描系统模块,基于嵌入式ARM9的步进电机控制系统模块等。并进行了微型生化检测仪检测系统光强重复性实验。实验结果表明,检测精度高,光谱扫描速度快,功耗低,实现了在检测波长范围内连续光谱检测,满足微型生化检测仪的应用需求。According to the requirements for detecting human biochemical parameters quickly and accurately in field, based on MOMEMS and embedded technology, a micro-biochemical detector test system based on mi- cro-spectrometer is designed. The system includes optical system modules, linear spectral scanning system modules and stepping motor control system modules based on embedded ARM9. And the light intensity repetition experiment of a micro-biochemical detection system is performed. Experimental results show that the system has high detection accuracy, fast spectral scanning speed and low power consumption. Continuous spectrum detection in the range of detection wavelength is realized and application requirements of micro-biochemical detectors are met.
