Non-Contact Measuring with Laser Triangulation Sensors

Riftek’s laser triangulation sensors have been designed for non-contact measuring and verifying displacement, dimensions, position, surface profile, vibrations, deformation, sorting, and sensing of technological objects. They can also be used to measure levels of liquid and bulk materials.

The series includes seven lines of models:

  • RF603—universal sensors with operating ranges of 2 to 1250 mm
  • RF603HS—high-speed sensors
  • RF609 (RF609Rt)—laser probes
  • RF600—large-base and long-range sensors
  • RF605—compact sensors
  • RF602—super compact sensors
  • RF60i—specialized laser sensors for pavement profile and texture measurement

  • Stable operation on wet surfaces

                                                                                   See detailed specifications

Operation

Operation of the sensors is based on the principle of optical triangulation. Radiation of a semiconductor laser 1 is focused by a lens 2 onto an object 6. Radiation reflected by the object is collected by a lens 3 onto a linear CCD-array 4. A signal processor 5 calculates the distance to the object from the position of the light spot on the array 4.

 

Applications

The Riftek laser triangulation sensors are used for various high-precision non-contact measurements:

  • Object dimensions 

 

  • Object and target displacements

 

  • Thickness

 

  • Profiling

 

  • Objects sorting

 

  • Runout
