Measuring point distance
Reading example for an angular resolution of 0.50° in figure 10
•
150m distance
•
For a distance intersection point at 150m, the measuring point distance is
approx. 1,100mm
•
For a distance intersection point at 150m and based on the characteristic curve
for beam diameter, the beam expansion is approx. 450mm
•
Result: Gaps of approx. 650mm during scanning, minimum object size >650mm
3.4.6 Minimum object size
For an object to be detected reliably, it must be hit completely by a laser beam once. If
the beam only partially hits, less energy may be reflected from the object see "Principle
of operation", page 11.
An object is then reliably hit completely at any time if it is at least as large as the
measuring point distance plus the beam diameter.
