RTSC:Real-TimeSurfaceCompensation<br />
WithRTSC,aworld-wi<strong>de</strong>uniqueinnovation,the<strong>de</strong>greeof<br />
reflection from the target is compensated during the ongoingexposureandinreal-time.Theexposuretimeorthe<br />
amountoflightproducedbythelaserisoptimallymatched<br />
to the currentlyrunning exposure cycle. It is only sensors<br />
from ELTROTEC which are equipped with this innovative<br />
real-time control and consequently they always achieve<br />

Adjustableexposuretime/measurementrate<br />
Fortargetswithlittlediffusereflectivitytheexposuretimecan<br />
be adjusted. The programed measurement cycle remains<br />
always constant, therefore the real-time data rate is<br />
guaranteed.<br />
