Preparing to Scan
45
When a scanning process is started in the range FAR and an object enters, the scan
is continued and "LASER: OFF" is displayed in the Scan Control status bar. The user
has two possibilities.
1. Remove all objects within < 0.3 m from the HDS6000 and start the scan once
again.
2. Choose the option CLOSE and start the scan once again. The monitored range is
now hardly greater than the housing of the HDS6000.
Measurement
noise
Measurement noise = scatter of measured values relative to a mean or reference
value.
The option
low
for the resolution level reduces measurement noise. This option
increases measurement time.
)
Measurements should be made basically in the mode FAR particularly if the
object range is large, because the mode CLOSE has the following differences:
•
The accuracy of range measurements of more distant objects is reduced
and measurment noise is increased. Also, intensities are lower because
the laser power is reduced.
