Abstract

Individual antenna-coupled IR bolometers have recently been demonstrated at wavelengths near 10 μm. 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.

摘要

最近已证明，单个天线耦合红外测辐射热计在波长接近10μm时能够工作。如果能够制造出天线耦合探测器的焦平面阵列（FPA），则有可能提高红外成像仪的性能。设计过程的第一步是根据调制传递函数（MTF）分析基于FPA的天线耦合成像仪的图像质量潜力。我们分析的关键步骤是开发一种串扰MTF，该MTF考虑了FPA中相邻天线之间的电磁耦合。我们发现，电磁串扰在天线耦合红外FPA中不会成为影响图像质量的重要因素。
