英文摘要：

In order to meet the demand of wide field of view （FOV）, wide swath width, and high throughput for the ocean spectrum, a new Fourier transform imaging spectrometer with wide FOV based on the image plane interference technologies presented. And the principle and expressions of the image plane interference are studied and educed.The optical system is designed and optimized based on the calculated detailed parameters. Dyson and double Gauss structures are used in the relay lens and fore optics respectively. Under the circumstance of 400-900 nm spectral range, 35.5° FOV, 320 km swath width, F/4, and 100 mm focal length, the average signal noise ratio （SNR） is greater than 100 and the modulation transfer function （MTF） of the current design is greater than 0.5 at 32 lp/mm. All the parameters are well satisfied by the present design.
