Abstract

A solid state (Charge Coupled Device) imaging system is described which satisfies the requirement for multispectral, high resolution, real time imagery. The system, using an earth resources survey satellite as its platform is configured to yield a 10 meter ground resolution with a 50 kilometer swath width at approximately 1000 km altitude. Four spectral bands ranging from 0.5 to 1.1 μm have been selected and are implemented by optically butting three 1728 pixel linear arrays (5184 pixel per band) on appropriate beam splitting prisms. The device employed, the Fairchild CCD 121H, shown in Figure 1, is a monolithic self-scanned image sensor utilizing two phase, buried n-channel CCD technology. The device has an element-to-element pitch of 13 μm (approximately 2000 pixel inch) and has been demonstrated to have a wide dynamic range (2500:1), Figure 2, low noise equivalent exposure and dimensionally precise photosite spacing. Consideration of focal plane design, geometric accuracy, image registration, temperature control, optical design, and noise figures are discussed. Particular emphasis has been placed on the unique properties of CCD detectors which allow for specialized post processing of the video for dealing with low contract scenarios. The paper concludes with new trends in specialized time delay and integration (TDI) mode imaging systems now under study and development at Fairchild.
