This is about NVGs (Night Vision Goggles)
I wanted to request for opinions for further clarity on the issue on electrical power utilisation by the NVGs (Please read- battery power) working on the principle of image intensification.
"Would that be true to say that during 'Better' lit up conditions by night, since the illumination enhancement required would be lesser as compared to a dark phase night (lets say) the consumption of battery power would be lesser."
Alternatively, possible hours of usage for a pair of batteries used only during the full moon days would be more than if they are used only during the'new moon' days- rest all conditions being identical.
My understanding of the topic indicates that this won't happen- the NVGs don't have a feedback system to 'maintain' a constant level of illumination through the phosphorus screen.
Well that's so far I can see.
Would appreciate comments
Thanks for the read anyway...
