Contact on an incoming top spin ball - speed, rotation and angles at 1500 fps

The physics of table tennis are difficult to understand at regular speed. Contact is *very* short - our tests show significantly less that 1/1000 sec -, but during that time a lot of energy is transferred - first from the ball into the rubber and then from the whole racket back into the ball. Angles, speeds and rotation determine the resulting ball trajectory, and the player must perform the stroke within a very tight tolerance to execute a successful shot.
The use of a super-high frame rate camera allows us to understand things a little more clearly.
