INTRODUCTION
This User's Guide section provides instructions for meas
uring
a velocity
alonij
the
Laser
beam.
Keep in
mind
that a
Ve
locity measurement is made by meas
uring
the cha
ng
e
in
position
of
one
of
the
Opti
cs
while
the
other
Optic
is
held stationary.
See
Appendix
A for
<1
desc
ription
of
the
principles
on
which this measurement
is
based.
To
make a
Ve
locity
mea
surement, begin
as
if
you
were
making a Distance measurement.
Most
instructions for the Velocity measurement are identic
al
to
those for a Distance measurement.
Values for s

of
course, y
ou'll
have
to

instead
of
