3. Information About the Sensor
Each configured ATOS sensor, in scan direction, has defined 3D areas
within which a measuring object can be scanned. In the following,
such a 3D area is called "measuring volume" (MV).
The measuring volume determines the distance between sensor and
measuring object and the set of lenses to be used.
In practice, depending on the measuring task, different measuring
volumes might be required.
Ideally, you have camera and projector lenses that are preadjusted to
your measuring volume. In this case, you need to perform no or just
very few steps for adjusting the sensor.
A complete sensor setup is only required if the corresponding set of
lenses has never been adjusted before or is decalibrated (wrong ad-
justments).
For a complete sensor adjustment, you need to adjust the angle rela-
tions of the cameras and set the focus and aperture of the lenses.
Then, the complete system is calibrated by means of calibration pa-
nels or calibration crosses. If the measuring volume is adjusted suc-
cessfully by calibration, you may start a measuring project.
The sensor adjustment is supported by the software. The software de-
termines all necessary parameter settings.
In order to achieve large, medium and small measuring volumes, the
sensors support two or three different camera positions (Small Objects
SO for small measuring volumes, 400 for medium measuring vo-
lumes, and 800 for large measuring volumes), see system types 2 and
table 3.1.
For camera position 400 or 800, you may install measuring volumes
with two different camera angles. For example ATOS II/400/MV560
with 27° and ATOS II/400/MV 1000 with 15°.
The eccentric stops ( , , , , ) are factory-preadjusted.
Never loosen these stops , , , or , as only an authorized
specialist is allowed to adjust them.

4. Lenses
The lenses shown in this example may, in some cases, differ from
those delivered in practice. Therefore, the statements made here have
to be used correspondingly.
All lenses are marked with L (left) or R (right) or P (projector). Left and
right are defined from the sensor view in normal operating position.
Never switch on the sensor if the projector lens still is equipped with
the lens cap! Due to the high light output, the lens cap and the pro-
jector lens may be damaged!

For the projector lenses, the aperture value is fixed and cannot be
changed.
Select a set of lenses matching the required measuring volume and
camera positions (e.g. SO, 400, 800), and screw it into the cameras
and the projector.
To avoid getting dirt into the cameras and the projector, always equip
the devices with lenses or blind caps, even when they are switched
off. When changing the lenses, fix the new lenses in place imme-
diately.
Screw in the lenses carefully by hand, lock the focus locking ring, if
necessary, to ensure screwing in without any problems.

7. Sensor Setup
7.1 General
In order to adjust the sensor, the complete system including the
ATOS software needs to be installed and the sensor must be
equipped with a set of lenses matching the measuring volume and
the camera position.
For each measuring volume (MV), the set of lenses are factory-
preadjusted.
If you have the respective set of lenses for each measuring volume,
setting up the sensor is easy as you do not need to carry out all the
steps referring to adjusting the focus and aperture!
You always need to perform a complete sensor setup if, for example,
the corresponding set of lenses has never been adjusted before or is
decalibrated.
7.2 Measuring Volume
Use the table in section 3.1 to determine a measuring volume.
You create larger measuring volumes with camera positions 400 and
800 and smaller measuring volumes with camera position SO (see ta-
ble 3.2).
Please check whether the cameras are in the correct position. How to
change the camera positions is described in section 7.3.
7.3 Changing the Camera Positions (Step by Step)
In order to change the camera distances, you need to open the sensor
housing. Therefore, disconnect all cables from the sensor.
It is not possible to operate the sensor without the upper part of the
housing!
In the following, we describe how to change the camera distance from
400 to SO.
When you are changing the distance from SO to 400 or when you
are changing to camera position 800, please proceed corresponding-
ly.
