EMISSION TYPE
The very low black/white difference of background suppression sensors allows to
detect a dark-coloured target presence, or absence, even onto a light-coloured
very reflective background. However, if the target is much smaller than the light
spot and smaller than the background area, the detection can be critical either for
the low resolution and for the ‘cross-eyed effect’ (excessive light reflected by the
background).
The narrow collimated light beam of the S62 LASER background suppression
sensor is the right solution able to offer the requested resolution and avoid the
cross-eyed effect, thus permitting the detection of the smallest objects or their
minimal movements, even in presence of large and reflective background area.
The LASER polarised retroreflex sensor of the S62 series, as well as increasing the
maximum operating distance, offers the improvement of the detection resolution
thanks to the smaller dimensions of the light beam respect to the LED emission
beam.
Basically, the mimumum detectable dimension corresponds to the emission beam
diameter at the detection distance. The maximum resolution can be obtained only
with microprismatic reflectors (0.8 mm microcubes), such as the small R8 suitable
for short distances up to 2 m, or the R7 and R20 models for distance up to 22 m.
