Abstract

Individual antenna-coupled IR bolometers have recently been demonstrated at wavelengths near 10 mm. If focal-plane arrays (FPA’s) of antenna-coupled detectors can be fabricated, enhancement of IR-imager performance is possible. A first step in the design process is to analyze the image-quality potential of antenna-coupled, FPA-based imagers in terms of the modulation transfer function (MTF). The key step in our analysis is development of a cross-talk MTF that accounts for the electromagnetic coupling between adjacent antennas in the FPA. We find that electromagnetic cross talk will not be a significant image-quality factor in antenna-coupled IR FPA’s. © 1996 Optical Society of America.
