Miniature Multi-channel Fiber Optic Spectrometer Design And Research

Spectrometer is an optical instrument which is based on the optical principle, and it is used for the the detection of spectrum of the material structure and ingredients. Firstly, the development, current situation of the research and application of the micro multi-channel fiber optical spectrometer is systemtically expounded in this dissertation, an integral design of the instrument which is based on the area CCD is also proposed; secondly, the design of the optical system is performed, including the grating selection and the determination of system parameters; thirdly, the type selecting of array CCD is completed in accordance with the principle of the detector, for the peripheral hardware circuits, some research of the timing simulation is completed too; in the final part of the paper, the instrument's software is discussed.More fibers instead of the traditional entrance slit and the area array CCD are used to design the multi-channel optical spectrometer in this paper, so the multi-channel measurement is realized, and the system's sensitivity has been significantly improved, then the system is more suitable for the detection of industrial scene spectrum.
