英文摘要	Aiming at development requirements of marine environment, ocean color and other fields, an airborne improved Dyson spectral imaging system with wide field of view and large relative aperture was designed. According to optical properties of marine environmental pollution, albedo value of different targets was used to estimate the signal-to-noise ratio (SNR) of target signal for expanding the working waveband of the hyper-spectral imager to the ultraviolet. A detector with large pixel size and an imaging system with large relative aperture were employed for the identification of weak signal of marine target; meanwhile, integration time was reduced to avoid detector saturation caused by excessively strong signals from inshore sand beach. The working waveband of the spectrometer was 0.32~1.05 m with relative aperture of f/1.8 and pixel size of 24 m24 m. Mutual interferences among slit, detector, optical filter and single lens were avoided through adding falcate correction lens. The design result shows that the optical transfer function at all wavelengths of the whole optical system is more than 0.83. In addition, both the smile and the keystone are less than 4% of pixel size. The designed imaging spectrometer is applicable to monitor marine environmental pollutions, especially marine oil pollution. 2017, Science Press. All right reserved.
