tubes. The former must have improved spectral response, the latter require 

 improved absolute response before full application to ground mapping 

 may be realized. Nevertheless, the not too distant future should bring 

 IR image tubes into serious contention with the so-called "point" detectors 

 for mapping operations. 



Equally important with new components are new techniques. Among 

 the most promising are the recent developments leading to stereoscopic 

 infrared pictures with simultaneous moving-target indication, multicolor 

 response (response to several well-defined spectral regions simultaneously 

 but with each response separated from the others and individually treated), 

 and advanced variable contrast control. Infrared reconnaissance was born 

 about ten years ago. The advances during this time and the work in both 

 research and development of the present make the outlook for the future an 

 optimistic one indeed.
