Multiple Captures
In many applications, you can improve opportunities for good reads by increasing the
number of captures.
The sketches below show dynamic multiple captures with no user-defined time delays
added between them. However, since a built-in or “overhead” capture time (15mS for CCD
and 30mS for CMOS) occurs after each capture, some spacing between captures will be
noticeable in higher speed applications.
• An ideal setup would look
like this where overlapping
symbols fall within or
mostly within the FOV. • This shows an acceptable
pattern where at least one
symbol can be expected to
fall within the FOV.
• The spacing here is not accept-
able since it is too wide to guar-
antee that any of the symbols
will fall within the FOV.
