On-board UI
The
FZW
includes an integrated user interface for operating the wa-
vemeter
independently
of
a
host
computer.
The
primary
display
shows the currently measured wavelength (Figure 3.1) in units that
can be selected via the up/down buttons.
Figure 3.1:
Primary
wavelength
display
showing
the
measured
wave-
length, saturation and contrast, as well as the device
IP
address.
The
saturation
is a measure of the optical power reaching the de-
tector, and the
contrast
is a measure of fringe quality.
In general,
higher saturation is preferred as this permits faster measurement,
however
oversaturation
(as
indicated
by
the
bar
turning
red)
will
degrade measurement accuracy.
Pressing the left/right buttons changes to an alternate display mode
(Figure 3.2), permitting diagnostic of the fringe pattern as explained
in
4.1, as well as displaying a rudimentary time-series of variations
in
the
measured
wavelength
over
time.
Pressing
the
central
OK
button opens the menu system (see
