I would like to know where I can purchase a piezoelectric-actuated mirror device, such as those used in a single-colour laser pattern (not scanning) projector eg. the kinds used at music venues/concerts.. I'm assuming these devices reflect a single laser beam with the piezo mirror according to some coordinates/defined rotations.
Is anyone familiar with these devices? I'm not sure where to read more about them, apart form supplier websites, etc.. I would like to control my own laser projector, creating patterns etc, using an arduino for prototyping.
What other kind of device can achieve high speed movements (>120Hz) for a move-pause-move-pause... type action.
Hope that makes sense.
