FLIR - reflexion problem |
|
|
| [Pamella]
I was testing all the positions we need to cover when moving the FLIR camera or the reflector. I tried to find out more about the problem so I tested the position without the mask, just with the old bridge and I got the same problems, in the middle of the screen we have a very good image but if we move we have the visualization problem and we don't see the reflection very well (intensity, emissivity) in FLIR.
For this test I used very low current (0.04 A) for keep everything safety.
I also think that problem is not in the focal point of the reflector because we can see very well in the center of the screen, but maybe it is because in the parabolic reflector the reflection in the focal point is "extremely" straight, so for you to see the reflection in this point you need keep close to the middle of the screen, to see around the reflector, at the extremes, we need to change the position for the cable or the light to "change" how the flashes of light reflect and thus achieve exactly the position on the camera. It is something like the sketch/ photo attached below. |
