Does anyone here have a ref on how to compare illumination by coherent
light against non-coherent light?

I'm thinking that a laser emitter might do better than my existing LED
emitters, but I don't know if the illumination is 1-1 or something
different.
We have an existing diode at 500-800mW output covering a +/- 60 degree
sweep in both directions, but I would actually prefer some compression
in the vertical axis.

Any ideas?
