Description

technical field [0001] The invention is applied in the field of outdoor spectrum measurement and analysis, and in particular relates to a portable static Fourier transform spectrometer based on OMAP-L137. Background technique [0002] With the rapid development of electronic information technology, the emergence of high-performance, small-volume, and low-power embedded systems has overcome the characteristics of large data collection and complex processing and calculation of Fourier transform spectrometers, and has provided a basis for the miniaturization of instruments. , Intelligent development provides a strong technical support. [0003] At present, compared with the grating dispersion spectrometer, the Fourier transform spectrometer has the advantages of high luminous flux, high wavelength accuracy, and wide spectral measurement range. It is the most powerful and versatile spectrometer in the near infrared, mid infrared, far infrared and submillimeter bands. instrument...
