Seems like shooting a laser through a canopy would be difficult. The
curvature of the Plexiglas and any imperfections would scatter the beam.


The housing rotates,and has a flat window,probably quartz or
germanium,depending on wavelength.
Like a thermal 'night-vision' system on a helo.

Such IR laser systems use a silicon mirror, such that the shape is variable.
