2D triangulation is novel measurement
alternative
If point laser sensors aren't sophisticated for a profile measurement application, and vision systems not fast enough, a new 2D triangulation system may be the answer.
The Scancontrol 2800 laser-line profile sensor can handle varied target surfaces In contrast to familiar point laser sensors, a line optical system projects a laser line onto the surface of the object to be measured

Laser triangulation outperforms vision systems
The latest laser triangulation sensors have inbuilt real time surface compensation algorithms that enable very high accuracy measurements at very high speeds of 10kHz or more.

Optical encoder aids pipework alignment
The OMC Pipe Profiler is designed to determine the dimension of pipe ends using an optical triangulation technique to estimate the distance to the surface of the pipe without touching it.
The back scattered light from the laser line is registered on a CMOS array by a high quality optical system.
Along with distance information (z-axis), the controller also computes the true position along the laser line (x-axis) from the camera image and outputs both values in the sensor two-dimensional coordinate system.
A moving object or a scanning sensor will generate three-dimensional representation of the object.
Measuring range on the z-axis is up to 245mm and on the x-axis up to 140mm.
Resolutions are 10um and up to 1024 points/profile, respectively.
Profile frequency is up to 4000 profiles per second and measuring rate up to 256,000 points per second.
The advantages of the system are its high accuracy, very high frame frequency, flexible field of view, high-performance signal processing unit and innovative CMOS-technology Scancontrol consists of a compact sensor and an intelligent controller connected together via cable of variable length.
The controller outputs measurement raw data computed from both axes (standard) as well as related values of geometrical features (optional).
Thanks to its exceptional speed of measuring and real time data output synchronisation Scancontrol is not limited in its applications and is ideally suited for industrial inline inspection.
The integrated FireWire interface enables Scancontrol to be fully controlled from a PC, while ensuring high data output rates and simultaneously preserving the bandwidth.
Applications include contour measurement, door gap alignment, position measurement, coplanarity measurement, profile acquisition, flatness measurement, groove measurement and robot guidance. Request a free brochure from Micro-Epsilon UK ...
