I think I should have said “optic” in place of “lens”. The crystal is the portion that is being oscillated to divert the beam. It could be that this is exactly the same principle being used by the referenced experiment but with much higher powered acoustic equipment.
Doesn’t an AOM typically have a lens?
Revit is a pretty commonly used architectural tool now.
Stratasys’ J850 totally has this capability. Full color printing with variable durometer elastomers.
