Re: [Paparazzi-devel] IR Sensors FOV

The sensor FOV is typically around 60-100 deg, depending on brand.  Everything 
emits heat, so you should try to keep the view as unobstructed as possible.  
There is of course no way to mount the sensors such that they are perfectly 
unobstructed and a complex set of calibration factors exist in the code to deal 
with this.  Just be sure to keep any obstructions symmetrical, particularly 
difficult with pitch, and try to avoid having sun-heated surfaces in the FOV - 
such as the top of a wing, tail, or fuselage.

Most importantly, keep any video/data transmitters away from the sensors and 
their wires.

Does anyone know what the FOV of the IR sensors are? I looked around and 
couldn't find it. Do I need to worry about placing things (which don't 
emit heat) in the IR sensors FOV  as long as they are not directly in 
the line of sight? It seems that tuning might take care of this but I'm 
not sure.
