Making an oscillatory motion happen for a mirror
Making an oscillatory motion happen for a mirror
(OP)
I would like to invite suggestions for a +/-20 degrees oscillatory motion for 300 mm dia/8 mm thick aluminium mirror at 5-15 Hz.
The main problematic requirement is the uniform velocity of excursion throughout the travel of the mirror.

Do you want sinusoid, sawtooth or triangle motion?
Can't you reduce the mirror size ? Why not ?

This won't drive your mirror that big but might give you some ideas. Perhaps going to a pellicle type system would lower the mass enough for you to drive something that big in diameter.
Good luck and let us know how you solve this!

what you want and find on other way to do it.

You can rotate the mirror very fast, you can make it as large as you want, and the angular velocity is constant.
