Spectrum detection technology and spectroscopy instruments experienced nearly a hundred years of development, in the modern scientific experiments, biological research, medical and pharmaceutical research, industrial and agricultural production, defense, astronomy and other fields has been an extremely wide range of applications. With the rapid development of modern science and technology, the traditional spectrometer has been unable to meet the current needs of the development, and many studies, the application of the field of spectroscopy instruments made small, miniature, faster, easy to use and flexible, high cost performance higher requirements . Therefore, miniature multi-channel fast Spectrometer Spectrometer become an important trend in the development of one. The project designed a plane grating used as spectral components as a linear CCD detector elements, and USB2.0 interface based on single chip multi-channel fast miniature spectrometer The spectrometer is small size, high speed, high precision, with plug and play characteristics, real quickly to a plurality of spectral parameters were measured, and can be used for other instruments secondary development. Paper first reviews the spectrometer overview of the development of the current common spectral measurement methods are compared, and proposed features of the spectrometer and research significance. The spectrometer then introduced to test some of the parameters related to brightness, color theory. Then the overall structure of the system were the introduction of a clear framework for the structure of the system, through three specific aspects of the system introduces the composition and implementation. First, the spectral structure of the system introduced, and the spectral components were analyzed. Second, detailing the high-speed spectral data acquisition hardware system and gathering the various components of the implementation process. Third, the introduction of the microcontroller firmware and PC software design, made communication, control, acquisition, data processing methods. Secondly describes the instrument calibration methods and measures, and the results were compared with the advanced equipment to verify the system's overall performance, in addition to the spectral power from the impact of uncertainty affecting the performance of the instrument were analyzed. Finally, this paper summarizes the work done, put forward the need to strengthen and improve future work. The actual use of authentication, the instrument yielded satisfactory results, to meet the requirements of spectral analysis, the study achieved the expected goals.
