Here is a simulation for a 24 KHz (bidirectional, so 12khz fundamental) scanner with a 1mm FOV: https://imgur.com/a/PqkV47Q The peak velocity is ~500nm per laser pulse, or about 40 meters per second. The right axis is how many pixels the spot displaces, assuming 2048 uniformly spaced pixels per line.
