Abstract:Fourier transform imaging spectrometer is a new technic, and has been developed very fast in recent ten years.When it is used in satellite, because of the limit by the data transmission, the authors need to compress the original data obtained by the Fourier transform imaging spectrometer, then, the data can be transmitted, and can be incepted on the earth and decompressed.Then the authors can do data process to get spectrum data which can be used by user.Data compression technic used in Fourier transform imaging spectrometer is a new technic, and few papers introduce it at home and abroad.In this paper the authors will give a data compression method, which has been used in EDIS, and achieved a good result.
