Functional Principle, Technical Data
3.1
Short Description
The optoNCDT 1900 operates according to the principle of optical triangulation, i.e. a visible, modulated light spot is projected onto
the surface of the measuring object.
The diffuse part of the reflection of this light spot is imaged on a spatial resolution element (CMOS) by a receiver optic arranged at a
certain angle to the optical axis of the laser beam.
A signal processor in the sensor calculates the distance between the light spot on the target and the sensor from the output signal of
the CMOS element. The distance value is linearized and output via the PROFINET interface.
