flashes as instantaneous strobes while they have duration.
Dwight, I think it's worse than that. There's also the idea of
"persistance of vision" that gets in the way and also makes the
strobe disc work--our eyes do not have instantaneous response and the
only reason a strobe disc really works is because a fixed pattern is
drilled into our optic nerves many times per second. Were this not
the case, one could have a 45 RPM strobe disc, not with 400 bars, but
with, say 4 or 50--but our eyes would likely not register these as a
single continuous event.
Of course I haven't tried this yet and I really should.
Cheers,
