10.8.2 Random modulation frequencies
The random modulation frequencies apply a method that changes the frequency with each image
(arbitrary frequency hopping). The frequencies are selected randomly.
f1
f2
f13
f12
The frequency set with random selection of modulation frequencies is suited for applications with the
following properties:
● mobile use of the devices (AGV, drone, vehicles, etc.)
● more than three devices in the field of view
When using the random modulation frequencies, interferences are possible. The interferences are
recognised and the affected pixels are marked as invalid.
► Use the fixed modulation frequencies by preference.
