What is the purpose of the interruptions?

They cut off the light before the spot has a chance to move to the
center, as Seto's theory predicts it will if the light beam is
left on.

Sigh....my theory says: the leading portion of a light beam will miss
hitting the hole in the cover plate due to the absolute motion of the
detecting surface and the cover plate.

Sure. And with the interruptions, you have LOTS and LOTS of
leading edges.

leading edge! leading edge! leading edge!

At a distance of 100 meters, as I recall, it takes 2.7x10^-8 sec
before the beam will shift enough to hit the hole in the cover
plate. So keeping the pulses only 10^-8 sec in duration will
mean that the discontinuous beam never hits the hole.

You didn't have any problem with this concept when I presented
10^-8 sec pulses emitted at a rate of 1000/sec on the "I need
help" thread:

specfied
a continuous laser. BTW that's the reason for the Uncertainty
Principle....the absolute motion of the detector makes a short pulse
of light (or a photon) to miss the detector and that's why you can't
detect the velocity and the position of a photon simultaneously."

Would you prefer programming the AWG for 1000 pulses/sec instead?
That's fine with me.

There will certainly be less problems with heating, and given
that I haven't yet found a commercial Kerr cell with liquid
cooling, that would actually be preferable.

How about 1 pulse/sec?

There is a clock; it's regulating the Kerr cell shutter. Jerry's
version detects that the spot is in a different place when the
laser is modulated on-and-off than when it is left on. That is,
if Seto's theory is right.

Ken, Jerry's version is much simpler, and if your theory of what
should happen in your version is right, then his should work too.
