  • Page 14: Functional Principle, Technical Data

    Functional Principle, Technical Data Short Description The optoNCDT 1750 uses the principle of optical triangulation, that is, a visible, modulated point of light is projected onto the target surface. The diffuse part of the reflection of this point of light is displayed depending on distance on a position-resolv- ing element (CMOS) by an receiver optic which is arranged to the optical axis of the laser beam in a defined angle.

  • Page 15: Real Time Control (Rtsc)

    What is more, it does so in a range from almost total absorption to almost total reflection. The RTSC (Real-Time-Surface-Compensation) allows an accurate real-time surface compensation in the measurement process with a high dynamic range. optoNCDT 1750 Page 15...

  • Page 21: Installation

    5.1.2.1 Light from other Sources Thanks to their integrated optical interference filters the optoNCDT 1750 sensors offer outstanding perfor- mance in suppressing light from other sources. However, this does not preclude the possibility of interference from other light sources if the objects being measured are shiny and if lower measuring rates are selected.

  • Page 22: Color Differences

    If the objects being measured are fast moving and the measuring rate is low, it is possible that movement blurs may result. Always select a high measuring rate for high-speed operations, therefore, in order to prevent errors. optoNCDT 1750 Page 22...
