A focal-plane-array chip designed for real-time, general-purpose, image preprocessing is reported. A 48 X 48 pixel detector array and a 24 X 24 processing element processor array are monolithically integrated on the chip. The analog, charge-coupled device-based VLSI chip operates in the charge domain and has sensing, storing, and computing capabilities. It captures the image data and performs l...

The eeciency of single dish mapping and synthesis array mosaicing can be increased by completely sampling the information in the antenna's focal plane. This requires a densely packed array of electrically small elements. Each telescope beam is formed with a weighted combination of signals from seven or more elements. This has the added advantage of correcting for large scale reeector distortion...

The potential of focal-plane signal processing for space-borne scientific imagers is discussed. Significant improvement in image quality and consequent scientific return may be enabled through the utilization of focal-plane signal processing techniques. The possible application of focal-plane signal processing to readout noise reduction, cosmic ray circumvention, non-uniformity correction, and ...
