An Infrared Television System for Hydrogen Flame Detection 
The problem: 
How to detect, with a TV monitoring system, a 
hydrogen flame burning in a bright sunlit environ-
ment. 
The solution: 
Use an infrared sensitive vidicon camera system 
utilizing a single camera operating in the near infrared. 
How it's done: 
Flame produced by hydrogen burning in air is not 
visible to the human eye because the emission 
spectra is outside the band in which the eye is sensi-
tive. A thorough analysis revealed that using an ultra-
violet vidicon produces poor results, but when an 
infrared sensitive vidicon is used the hydrogen flame 
is clearly visible. A narrow band pass filter (pass band 
centered about 2.8 microns) was added to the set-up 
which provides a great degree of control over the 
scene displayed.
