本文介绍新一代地球敏感器,这种敏感器采用新近开发的非制冷型红外阵列探测器。用这种阵列器件探测地球红外波段的热图像,随后进行图像处理,求出中心坐标。由于取消了扫描机构,这种敏感器与现今使用的地球敏感器相比,技术实现手段大大简化。由于要对敏感器定期进行重新标定,还保留一个活动部件,不过它是一种非常简单的粗部件。因此,敏感器的总体尺寸、质量和成本都大大降低。工程模型的研制须经功能与环境试验,这些工作目前正在伽利略公司(Officine Galileo)进行。
This article describes a new generation of earth sensors that use newly developed uncooled infrared array detectors. With this array of devices to detect the Earth’s infrared thermal image, followed by image processing, find the center coordinates. Due to the elimination of the scanning mechanism, this kind of sensor greatly simplifies the technical realization compared with the earth sensor used today. Due to the regular recalibration of the sensor, a moving part is still retained, but it is a very simple rough part. Therefore, the overall size of the sensor, quality and cost are greatly reduced. The development of engineering models is subject to functional and environmental tests, which are currently being carried out at Officine Galileo.
