Wow
Another great idea.
But how can u tell the difference between a good picture and a bad picture, if the camera jerks, the picture comes out jerky due to camera motion, since you don't know what the picture looks like, there is no way to compensate for it. is there ?


If the mirror isn't moving, the image moves. If you know the image is moving in a given direction at a given velocity,or it has moved to a certain position you apply a position signal to your servo to reduce the error to zero.

Actually probably better to look at error velocities rather than positions.

If you were REALLY clever, you do all this in the interframe period for the camera, so the camera always sees a fixed image when it starts an integration for the next frame.

Neat problem, classical solution for tip and tilt. No AI, No Fuzzy Just op-amps, luck and an 8052 !

Incidentally you have made me look much more closely at my own image corrector for the scope, but we need to move at 20-30 Hz there ...
