3.3 Operation principle
Figure 3-4 Scanning range
Figure 3-4 shows the scanning range of SE2L. Protection zone and warning zones
are configured using
the SLS Project Designer application software. Any object or human beings entering the protection zone will
lead the OSSD signal to change from ON-state to OFF-state. Similarly, an object detected in the warning
zones will lead the warning signals to change to OFF-state.
Distance to the object is measured using the Time of Flight (TOF) principle. Pulsed laser beams are
radiated into the scanning range of 270º by the rotating motor. These pulsed laser beams are reflected back
by objects inside the scanning range. The duration of reflected beams are used for distance calculation as
shown below:
Where, L
=
Distance of the object
C
=
Speed of the light
T
=
Time difference
