Paper Abstract
Hydrogen fires emit very little radiation in the visible band, indeed in daylight they
are effectively invisible. This is a serious safety hazard particularly in the aerospace
field where hydrogen is widely used as a rocket propellent.
A practical imaging system has been developed to detect the non-visible radiation that
these fires do give off.
The emission spectrum,atmospheric transmission, background emission and reflection
have been quantified under various conditions. This shows thermal wavelengths are well
suited for this application.
A low cost, uncooled, staring array TV compatible thermal imager has been optimised for
this. The resultant image is 'punched through' to super-impose the flame on a bore-sighted
visual TV image.
Finally the integration of this equipment into the sophisticated C.C.T.V. observation
system on the N.A.S.A. space shuttle launch pad is discussed.
