Author Affiliations +
An imaging spectroscopy with new principle is presented in this paper. We call this imaging spectroscopy as LASIS (large aperture static imaging spectroscopy). The LASIS possesses the advantages of lighter weight and higher sensitivity. It can be widely used for the mitigation of natural disasters such as forest fire, earthquake and flood, for the general survey of crops distribution, insect pests and estimation the yield of crops. First, a brief depiction of Imaging Spectroscopy and its application is introduced in this paper. Second, Principle of LASIS is presented along with its main innovations and characteristics. Third, an instrument designed for testing its principle is introduced, which have 85 millimeters focal length, 4.2 degrees field of view, 1:8F number. At last, the experimental results with 100 numbers of spectral bands are given. We can conclude form the results that the LASIS can solve the energy problem of Dispersive imaging spectroscopy because it really have the advantages of high throughput and high sensitivity.
