Abstract
Earth observation is an important field of infrared remote sensing. Hyper-spectral remote sensing play an important role in weather forecast, environmental protection, agricultural production and geological survey. Now, Fourier-transform spectrometer (FTS) based on theory of Michelson interferometer has successfully been used to view the earth as a satellite-based instrument. The technology of FTS is an important research direction. This paper state the application of the FTS and give the analysis and research on interference signal sample and acquisition, in addition, it give a solution in which FPGA is used to complete the parallel capture of signal. In a conclusion, this design can accomplish the multi-channel and high-speed interferometer signal acquisition and transmission which is a base for further spectrum inversion and application.
