摘要

Second-generation Global Imager (SGLI) has a multi-channel in the wavelength range from near-UV to thermal infrared. SGLI consists of two sensor units, Visible and Near Infrared Radiometer (VNR) and Infrared Scanning Radiometer (IRS). We use three integrating spheres for each wavelength range in radiometric tests. The materials of inside wall of sphere are polytetrafluoroethylene (PTFE) and barium sulfate for ultraviolet-visible to near infrared channels, and gold for shortwave infrared channels, respectively. This paper describes the Proto Flight Model (PFM) radiometric performance using these integrating spheres.
