Prototype Design for NPSAT Visible Imager

Abstract

The objective of this work was to design and construct a prototype imager for the NPS remote sensing satellite. This project is a low-earth orbiting satellite designed to image the earth in VNIR and LWIR at a resolution of 100-200 m. The specific imager design considered here is the VNIR instrument, designed to image the daylit earth and atmosphere, as well as the relatively dim aurora (northern lights) at multiple discrete wavelengths. This project defined the desired wavelengths to be: 427.8 nm, 470.9 nm, 557.7 nm, 630.0 nm, 636.4 nm, and 844.6 nm. A Kodak 763 X 512 CCD was implemented into a push-broom scanner design appropriate for our mission. Design optics are for a nominal F/2, 90 mm Leica lens. The prototype was completed and demonstrated to operate.
