Operational modular imaging spectrometer (OMIS), an advanced optical mechanical scanning imaging spectrometer was developed.
介绍研制的一种先进的光机扫描光谱成像仪，即实用型模块化成像光谱仪（OMIS） 。

In this way, after atmosphere correction the signal-to-noise ratio characteristic of OMIS images can reflect that of the OMIS instrument sufficiently.
这样在大气订正后，图像的信噪比性能充分反映出遥感仪器的信噪比性能。

Combining the thought dimensioned above, with discrete cosine transform-based and DWT-based compression algorithms, the OMIS multi-spectral images are compressed.
