| 摘 要： | 基于交叉非对称的czerny-Turner结构, 研制了一种微型光纤光谱仪, 采用光栅分光、线阵CCD探测光, 基于复杂可编程逻辑器件及PC104设计CCD数据采集电路, 采样结果通过PC104总线上传至PC104工控机, 光谱仪及数据采集电路集成为一光谱仪模块, 约为96mm(宽)×104mm(长)×18mm(高), 该模块与PC104工控机之间通过PC104总线以“针”和“孔”形式层叠连接, 在具有体积小、功耗低、采样速度快等优点的同时还具有极好的抗震性, 非常适合于野外恶劣工作环境下的在线使用。将其应用于海水中铁等痕量元素及营养盐在线检测仪, 试验结果良好。

| Abstract: | A micro-fiber spectrometer based on non-symmertrical cross-czerny-turner optical structure is developed. In this spectrometer, the light signal collected and transferred by the fiber is dispersed by grating and then measured by a 2048-element line CCD array. The analog signals of CCD can be amplified and converted to digital signals by the data acqui-sition circuit of CCD that is based on the complex programmable logic device and PC104; the digital signals can be translated to the PC104 embedded industrial control block by the PC104 bus. The spectrometer and the data acquisition circuit of CCD have been integrated into a spectrometer module with physical dimensions of 96 mm (wide) ×104 mm (long) ×18 mm (high). Based on the PC104 bus, the spectrometer module and the PC104 embedded industrial control block can be in a cascade con-nection through the “needle” and “hole”. The spectrometer has such features as small volume, low power consumption, quick sample rate and excellent aseismicity among others, which make it suitable for field work under abominable conditions. The micro-fiber spectrometer has been used in an autonomous instrument for trace elements and nutrient measurement in seawater and the testing result is excellent. |
