I'd like to try to make my own instrument to measure the path averaged refractive index structure constant (Cn2) which is a measure of atmospheric turbulence in regards to optics.
Does anyone have experience with this field? I'm an engineer at a field testing facility for lasers and optics equipment and so I have access to other instruments like DELTA, and the BLS900/2000 which use different means of calculating the path averaged Cn2, but I haven't really thought of trying to make my own instrument till now.
The Delta seems to take a bunch of images and track features between them, then that feature jitter due to the turbulence is used to calculate the Cn2 / rytov Cn2 and the rytov number. I figure pursuing something like that would be the easiest, but I'm sure there are other ways of measuring it too.
Any thoughts?
