I am just working on go number 2 experiment of the X Y vibrating mirrors this time trying 2 solenoids as electromagnets ,i know the large one is fine for half line frequency,the small one is for the horizontal seems to work fine tried amplifying the resonance with longer plate not sure if that is a good or bad thing yet as in vibrating accuracy see when i do a laser test .

In the photos just putting it together may have to adjust the position of the electromagnets and such to get the laser reflecting correctly .

I also need to try resizing of the vibrating steel plates i am using more than likely 4 times the size they could be, the length is adjustable so thats not a real problem adjusting them i can see when it resonates best.

The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.

I did end up changing the position of the horizontal low frequency electromagnet just to get the laser reflecting right for these tests.

Adjusting the low frequency you get these Lissajous curves seems the vibrating plates are workable so far.

Just seeing one step at a time how it gos .

Had to adjust the design a little to get the laser bouncing off the mirrors right
