摘要 | Airborne ocean colour remote sensing urgently require wide angle and large relative-aperture hyperspectral imager. Based on the research objective of wide angle and large relative-aperture, an airborne hyperspectral imager optical system was designed using an off-axis two-mirror anastigmat telescope and a modified Offner spectrometer. The field of view of hyperspectral imager was 40, relative-aperture was 1/2.2, and working waveband was from 0.4 m to 1m. Relative aperture and image quality were improved by inserting a concentric meniscus in a classical Offner spectrometer. Ray tracing, optimization and analysis were performed by ZEMAX software. The analyzed results demonstrate that the MTF for different wavelengths is more than 0.67 at Nyquist spatial frequency 28 lp/mm, both smile and keystone are less than 6.5% of the size of pixel. It is easy for spectral and radiation calibration. The design results satisfy the requirements of specifications, the volume is small, mass is low, and is suitable for airborne remote sensing. |
