The edge filter for judging the interrupted
beam section can be adjusted to suit your
specific measurement requirements and the
measurement object.
On the ZX-GT, the interrupted beam section
is judged according to how many continuous
pixels of the CCD's 2000 pixels in the
receiver are blocked. These continuous
pixels act as the edge filter. By adjusting this
number of edge pixels, you can prevent
noise and increase detection sensitivity.
