Paper Abstract

A very high sensitivity scanning radiometer has been developed for remote sensing in the 8-12 μ.m spectral region. The paper describes this system which, under computer control, can automatically monitor the thermal emissions from one point or many points within a preselected field of view. The thermal data is displayed either digitally or in the form of graphs or as colour coded thermal maps of the area under inspection. This instrument offers a highly versatile scanning system combined with a thermal resolution much greater than usually available from current thermographic systems down to 1 mK. Furthermore, in addition to point, line and area scans, temperature vs time plots of single points may be produced. Many digitally recorded scans may be stored and quickly recalled for examination. The range of potential uses is wide and it is envisaged that the instrument would be particularly valuable in those applications requiring up to 100x the resolution of typical thermographic systems.
