A Study of Industrial Microwave Sensors for New Millennium

Abstract

Infrared and mm waves have become very useful for night vision equipments, heat seeking missiles, molecular spectroscopy and infrared astronomy. Among other things the trapping of infrared radiations by atmospheric gases is also the basis of green house effects. In infrared astronomy, we make study of astronomical objects by observing infrared radiations they emit. Such celestial bodies can not be seen from the earth, because they do not emit much visible light or that light is blocked by dust and cloud, which infrared radiation can penetrate. Thus infrared and mm wave devices have become a challenging issue in the coming time. So it becomes the duty of each and every science loving scholar to add a step in this direction.
