Explanation
In the "Reflection sampling" area, you can choose whether to
record a single sample, 50 cycles, or continuous samples.
Using the continuous display also provides you with an alignment
aid. You can use the displayed amplitude of the evaluated reflect-
ing object to check whether the sensor is optimally aligned with
the object. You will know this has worked when slightly varying the
alignment no longer increases the displayed reflection amplitude.
Note: For information about alignment and the amplitude height of
reflections, see also the "Reflectiveness of Materials" (see chapter
3) chapter.
You can use the "Display in graphic" area to set whether all of the
sampled reflecting objects are shown together or only the most
recently sampled object image is shown.
The "Start" button is used to start and stop reflection sampling.
After reflection sampling has started, the button changes to
"Stop."
• In the case of "single" reflection sampling, reflection sampling stops
after one measurement.
• In the case of "50 cycles" reflection sampling, reflection sampling
automatically stops after 50 measurements. You can stop it at any
time by pressing the button again.
• In the case of "continuous" reflection sampling, reflections will con-
tinue to be sampled until you press the button again.
The sampled object reflections are displayed in the form of thin
columns during and after completion of sampling.
The counter in the upper left corner indicates the number of reflec-
tion samples that the current graphic is based on.
You can save the reflection sample as a .CSV file, .XML file, or
.TXT file by pressing the "Save to file" button. In addition to this
data, sensor settings (parameter values) will also be saved. This
means it is possible to evaluate recorded data later "offline."
You can load previously saved reflection samples to the DTM by
pressing the "Load file" button, allowing you to assess or evaluate
the samples.
Note: You can only load a saved file when disconnected from the
sensor.
Clicking on one of the object reflection columns shown in the
graphic displays detailed information about the selected reflection
below the graphic.
You can use the "Clear reflection sampling" button to clear the dis-
play area and restore it to its original state.
You can use the "Rescale diagram" (magnifying glass) button to
enlarge the view along the x-axis up to 5-fold in 100 % incre-
ments.
If magnification is set to more than 100 %, the displayed area can
be shifted along the x-axis (by scrolling) to be able to obtain a
magnified view of sections of the entire sample area.
To do so, right-click on the x-axis, keep it pressed and move left or
right with the mouse.
