6.1 Factors affecting the measurement range
Laser distance sensor is a new of non-contact optical measuring equipment. Its
measuring range and accuracy will be effect by many external environmental
factors. So actual measuring result might be different with typical value which is
measured in standard environment.
The following factors will effect actual measuring range:
Effect Factors
Increase measuring range
Decrease measuring range
Surface of
target
Bright and smooth surface with
good reflection, like target plate
Deep color and rough surface,
like green or blue target surface
Air visibility
Clean air
Dust, fog, storm and rain, snow
Ambient light
Dark environment
Target exposure to strong light,
like sunlight in midday
Laser emission
Laser emission lens and
protection glass keep clean and
smooth
Laser emission lens and
protection glass get dirty or
scratched
In conclusion, the best measuring result will be happen in a dark environment
and with a good reflection target. We strongly suggest to use a target plate when
laser distance sensor works in a poor environment.
We also suggest to keep laser emission lens and protection glass clean with a soft
cloth before start to using.
