Beam splitters and baseballs

[P3D Lew Clayman/K Szafran <kandlew@xxxxxxxxx>]

Can anyone help a newbie trying to learn about beam splitters?  It seems an
efficient way to "get dimensional" 
ie, leveraging existing technology and all that.  Especially, is there a
splitter that works well on any digital camera?

Re the discussion on neural processing time and the ability to locate a
baseball in three-space - the correct pitching distance is 60'6", meaning
that a 100mph fastball is en route for about 400ms.  Thus either (a) the
batter can locate the ball in 3D, decide to swing, and swing, all in 400ms;
(b) the batter anticipates the trajectory, based upon experience and other
clues such as pitcher's posture, grip, delivery details, game situation,
etc.; or (c) some combination of (a) and (b).  I'm not sure what this
indicates in terms of neural processing analysis, other than to point out
that whatever baseball is, it isn't a controlled experimental situation.
Also note that these are selected and trained specialists, hardly
representative of the general population - maybe they "see faster" than the
rest of us.

For those of you outside the baseball zone, that's 18.44m at 161 km/hr, from
bowler to batsman.  It's still only 400ms, though.

Oh, and I still want to know about beam splittters.  Thanks.
