By using eight linear array CCDs as the photo detector,a new type of multi-channel fiber-optic spectrometer was presented to measuring eight channel spectra simultaneously and swiftly.In the system,a FPGA was acted as the controlling unit to generate time sequence and the spectral data were processed by the DSP,it communicated with the PC by its inner USB module.This paper introduces the structure of the whole system and the method of the optical system design,also describes the process of spectral data collecting under the control of the DSP and FPGA.A specific FPGA programming technique is brought forward to settle the capacitance effect inside the IC chip to prevent signal interference between two adjacent channels.The results show that the system has a good long-term stability,a large signal dynamic range and a higher SNR.The spectrometer can be used to measure spectrum or related parameters in various situations.

>=Multi-spectral imaging technology, integrated with the capabilities of spatial imaging and spectral detecting, can acquire both spatial information and spectral information simultaneously, thus it is highly emphasized in acquisition and process of image. Based on the narrow band multi-spectral imaging technology a eight channel multi-spectral imaging system is set up which can acquire eight images in real time and eight Spectral responses ranging from 420 nm to 940 nm for a certain element. Each image must be aligned before more Spectral Reflective Ratio can be obtained by interpolation .After calculation, Spectral Reflective Ratio and related color parameter of each point can be obtained.

The system can be widely used in the field of moving target recognition and accurate color reproductions for acts.

光谱成像技术可以同时从光谱维和空间维上获取被测目标的信息,即结合了空间成像系统和光谱检测系统的功能,因此近年在影像获取与处理领域中倍受重视。本论文基于窄带多光谱成像技术建立八通道CCD多光谱成像系统,它能够实时采集八个通道的图像,获得波长分布从可见到红外(420—940nm)八个波段的光谱响应值。在此基础上对图像进行位置配准、反射率定标、采用插值算法获得其它波段光谱响应值,最终能够获取图像中任意一点的光谱反射率及颜色参数。实验结果表明,本文使用的三次样条插值法对原始光谱图像进行平滑操作的方法是有效的,能够以一定精度模拟出目标物点的真实光谱特性。该系统在动态目标检测识别、艺术品评价复制等领域有着广阔的应用前景。
