This paper describes how, in spite of occasional performance limitations generally due to process defects, large-area solid-state image sensors can be applied to scan pictorial data. First, it is estimated to what extent the direct imaging of pictorial matter onto a defective area-scanning device for acceptable scanning quality is possible. A novel concept is then proposed in which the optically generated Fourier-transform hologram of a picture rather than the picture itself is imaged onto a defective solid-state photosensitive array, scanned, digitized, filtered, and reconstructed by fast Fourier transform (FFT) techniques on a digital processor. The operating principle is discussed and the effects of scanner defects, digitization, and filtering on the scanning quality are investigated by computer simulation.
