摘要

为了有效地实现光谱仪的便携式设计,文中采用FPGA便携式光谱仪。FPGA采用Altera公司的CLCLONE IV系列的EP4CE30F23C8N芯片,CCD采用东芝公司的TCD1304。系统机上的数据使用Matlab进行去噪处理,绘制成光谱曲线,系统选用汞灯作为标准光源进行系统校验,利用汞灯的5个标准光谱特征峰确定光谱仪的谱线校验系数。测试结果表明,光谱分辨率可以达到10 nm,系统可以实现可见光波段的光谱测量,具有较好的实用性。
        A practical portable spectrometer is established by adopting a modular design scheme combining the FPGA with the linear CCD,so as to effectively realize portable design of the spectrometer. The EP4CE30F23C8N chip of Altera′ s CL-CLONE IV series is used for the FPGA. Toshiba′transmission of spectral data were completed in the system. The data transmitted to the PC is denoised with Matlab,and drawn into the spectral curve. The mercury lamp is selected as the standard light source for system calibration. The spectral line calibra-tion coefficients of the spectrometer are determined by using five standard spectral characteristic peaks of the mercury lamp. The test results show that the spectral resolution ratio can reach 10 nm,and the system can realize spectral measurement of the visi-ble light band,which has a good practicability.
