Paper Abstract

Parametric studies of the imaging properties of sensor systems using high-resolution charge-coupled device (CCD) arrays require that the spatial frequency content of the images presented to the CCD be well characterized. We describe a laboratory system based on an all-reflective 1:1 optical relay which provides diffraction-limited images over a useful field up to 100 sq mm area, at any wavelength, at speeds of up to f/5. The design form employed, an Offner relay, has a number of inherent advantages. Additional features have been incorporated for the convenience of experimenters. While presently static, the system can be adapted to simulate scanned sensors. The imaging capability of this relay was verified using a digital camera system built around a large-area (1320 by 1035 pixel), high-resolution (6.8 sq micron pixel size and pitch), Kodak 'megapixel' CCD array.
