摘　　要：随着人们对光谱测量仪器灵活性、微型化的要求,便携式光纤光谱仪在实际生产测量中的需求也越来越大,对其测量性能的要求也越来越高。根据光纤光谱仪的测量原理,利用波长与CCD探测器单元格一一对应的关系,提出了一种波长校正的方案,波长校准精度可以达到0.5nm,重复性达0.1nm。With people＇s requirement for spectrometer are agility and micromation, portable fiber spectrometer is needed more and more widely in practical measurement, and the requirement for its measurement capability gets more and more higher. According to the measurement principle of the fiber optic spectrometer and the corresponding relationship between the wavelength and the CCD detector＇s cell, a wavelength correction method is put forward in this paper, the wavelength precision can reach 0. 5nm and the repeatability can reach 0.1 nm.
