I’ve mentioned BeamWatch before.
It’s an innovative technique for profiling high power lasers (1 kW and up).
I’ve even touched on the underlying Rayleigh scattering effect that makes this possible.
But how does this really work?

CCD camera beam profilers are very sensitive to light.
So what happens when we consider ambient light? How about other light sources in the area, such as laser pumps?
There are two issues that can be caused by unwanted light getting into the camera:
