Laser galvanometer scribbles from discarded pen recorder from dumpster diving at the Physics Dept. Yes, it looks two dimensional as I moved the camera in a circle during the exposure. “Continue reading” for more galvanometer information. Continue reading
I arranged two mirror galvanometers to give two dimensional control of a 10mW HeNe laser beam. “Continue reading” for further information and another 9 photos. Continue reading
I have made a third much smaller nitrogen laser but with higher power and it can be fired a lot faster.
