Multi-point Triangulation

Point triangulation provides an elegant solution for applications requiring measurement at a single point on a surface, or along a single line on a part moving on a conveyor. More complex applications requiring profile measurements on 3D surfaces need measurement data from multiple points across the surface to monitor a complete surface profile. One approach to multipoint measurement is to mount a number of point sensors in a line across the surface. This approach has several disadvantages. Each sensor in the array must be individually mounted and interfaced to the host computer (both physical wiring connections and also communications ports with related software). Global calibration aligning each sensor in a common coordinate system is necessary. The result is a complex and costly implementation.
     
To dramatically simplify implementing these applications, LMI offers a number of multi point sensors, which project many laser lines onto the surface being measured, all housed in a single, factory globally calibrated package. Sensors are available with up to an impressive 76 laser points projected from a single sensor package. Integration requires mounting only one sensor, connecting one cable, and as many as 76 surface profiles are provided. Mounting and connecting a single multi point sensor provides the same information that would be provided by implementing as many as 76 individual point sensor sensors.
