摘要：

Hyperspectral imager is a useful optical instrument for remote sensing of Earth environments. The traditional hyperspectro imager consists of (1) object lens system, (2) spectrometer system, and (3) imaging system. The object system of hyperspectro imager requires wide field and high spatial resolution. The spectrometer system is a dispersive element to diffract the input light into light in continuum spectrum. The specification of our imager system: size 25x12x15 cm3 and weight 2.5 kg, wavelength range 450-650 nm with approximated resolution 1 nm. We will show wavelength calibration and preliminary results for the calibration procedure and data format in the laboratory. Besides, we also introduce an innovative design especially for limited volume and lightweight. For our preliminary design of TMA, the focal length is 150 mm with aspheric lens system in the optical non-axial system in 2U space. We will discuss the challenges of designing, manufacture, and assembling.
