休斯公司为下一代焦面阵研制了一种新型“超晶格”材料结构,红外传感器的性能似乎将得到改进。这种人造晶体分子结构具有截然不同的特性,这些特性包括光学吸收率很高,使它对光特别敏感,而且电子背景噪声电平很低。有了这些特性就可产生出极高质量的图象。其结果是:夜视系统在黑暗中看得更远更清楚了,地球观察卫星拍摄出地面更细小的特征。休斯公司对这种新型晶体超晶格材料的继续研究,最终可能会导致出新一代的高性能电子器件。

Hughes has developed a new “superlattice” material structure for the next generation of focal plane arrays, and the performance of the infrared sensor seems to be improving. The artificial crystal molecular structure has very different properties, including high optical absorptivity, making it particularly sensitive to light, and the electronic background noise level is very low. With these features can produce very high quality images. As a result, the night-vision system looks farther and clearer in the dark, and Earthwatch satellites shoot finer features of the ground. Hughes continued research into this new crystal superlattice material could eventually lead to a new generation of high-performance electronics.
