Abstract: Spectrometers are an important scientific instrument that uses optical principles to observe, analyze, and process the structure and composition of substance. The traditional optical spectrometers have complicated structure and large volume, which is limited in many application area, so the miniaturization of the spectrometer is an important trend in future development. The traditional spectral analysis technology can utilize the absorption or reflection characteristics of light on a substance to obtain the actual composition and structure of the substance by analyzing the spectrum. This project carries out two parts: the first part is to build a miniature spectrometer system based on the linear array CCD, and through continuous debugging to achieve a high resolution about 0.067 nm/pixel; the second part is an optical spectrometer based on smartphone, which uses CMOS camera as the optical signal receiver, and the lightweight design of spectrometer is realized by wireless network and compact design. This dissertation mainly expounds the optical path design of optical spectrometer, the hardware and software designs of spectrometer based on the linear array CCD, the hardware and software design of smartphone spectrometer, and the spectral comparison, error analysis and summary of experimental results. Finally, two sets of spectrometer experimental prototypes of certain resolution, measurement range, and integration were developed.
