摘　　要：现有商用光谱仪虽然能够以极高的光谱分辨率对目标物进行测量与分析,但是存在系统复杂、体积庞大和价格昂贵等缺点,难以满足现场检测等应用需求。为了解决该问题,提出了可用于现场快速检测的小型化多通道光谱测量系统。相较于传统光谱仪,提出的小型化多通道光谱测量系统不仅结构紧凑而且光谱分辨率高;另外,多通道设计可以用于同时检测多个样品从而进一步提高测量效率。通过对罗丹明6G和禽流感病毒抗体的检测,证明该小型化多通道光谱测量系统可以实现各类目标物的准确定量测量。由于该小型化多通道光谱测量系统具有灵敏度好、分辨率高、体积小等优点,因此其有望应用于现场快速光谱检测应用中。Although current commercial spectrometer can measure and analyze the detecting targets in extremely high spectral resolution,it still suffers from many disadvantages such as complicated system,bulky size and expensive costs,which are difficult to meet the needs of field testing.In order to solve these problems,a portable multi-channel spectral measurement system for rapid on-site detection was designed.Compared to the traditional spectrometer,the proposed design was not only compact,but also had rather high spectral resolution;and additionally,its multi-channel configuration supported simultaneous detection for multiple samples to further improve the sensing efficiency.Proved by the detecting results on Rhodamine 6G and avian influenza virus H7N9 antibodies,the proposed portable multi-channel spectral measurement system could quantitatively measure various samples in high accuracy.Because this system has the advantages of good sensitivity,high resolution and small volume,it is expected to be used in the rapid on-site spectral detection application.
