Paper Abstract

The typical Multispectral Linear Array (MLA) Instrument mission would be to gather high-resolution, radiometrically accurate earth resources data in several spectral bands over a prolonged period of time. These bands would include the visible (VIS), near infrared (NIR) and short wavelength infrared (SWIR). Silicon charge-coupled imaging devices (CCDs) can be assembled into contiguous pixel focal planes which will cover the VIS/NIR region and operate reliably for several years in a space environment. A typical MLA focal plane would have approximately 12,000 pixels, with a pixel-to-pixel registration requirement on the order of ±0.1 pixel. Fairchild Weston Systems has developed the technology to assemble such focal planes. This paper describes that technology, and addresses the problem of polarization sensitivity associated with certain types of focal plane assemblies. Since one of the environmental factors affecting the long term (5 years or more) operation of CCD MLA focal planes is space radiation, the paper also discusses radiation effects on CCDs, and describes a practical solution to the problem through the use of shielding.
