2D-Measurement (OPTISCAN / OPTIMESS 2D) is a Non-contact Laser Measuring System that operates in a non-contact process.


With the help of its international partners, ADOR Tech designs and manufactures the dimensional laser scanner OPTIscan / OPTImess 2D, operating in a non-contact process, a unique model of the OPTImess detector. The operating method of the OPTImess sensor is mainly based on observing an object at a fixed point; the OPTIscan / OPTImess 2D works according to the same principle; however, the measuring point is scanned along a line.

Measuring method

1- OPTIscan measuring method:

 In the OPTIscan, a scanning mirror system will realize the measuring line. The reflected beam is directed toward the detector using a second mirror on the same axis. The vertical distance will be calculated through the triangulation principle.

The horizontal position is determined via an angle measuring system at the mirror's rotation axis. The advantage of the OPTIscan is that in every measuring point, the full laser power is available and is not distributed along the line length at the sheet of the light sensor.

2- OPTImess 2D measuring method:

The line will be generated through an optical widening in the OPTImess 2D (sheet of light method). The bar will be imaged on a CCD matrix. The distance measurement is based on the triangulation principle.

This type of sensor is advisable for many applications, where a standard OPTImess sensor would have to be moved horizontally by a me­cha­nical device. For applications with a small scanning width (< 400mm), it is possible to use the OPTIscan /OPTImess 2D. As a result, reducing the costs of a complex mechanical system is possible.

2D-Measurement (OPTISCAN / OPTIMESS 2D) abilities


In this case, the OPTIscan / OPTI­mess 2D detects the step's horizontal position, "Xo," and its height, "Eo."


This example is similar to Edge Gauging, except that OPTIscan / OPTImess 2D and the object's surface are not parallel. Also, in this case, it is possible, as in Edge Determination, to measure "Xo" and "Eo." In addition, the angle can also be measured. This angle is essential if a robot or manipulator has to be adjusted at an angle to the measuring object.


The application cases illustrated in this example are expansions of the previous abilities (edge gauging and location surveying), whereby the surfaces to be measured are no longer placed directly on each other.

With the OPTIscan / OPTImess 2D, it is possible to measure the height “Ho” as well as “Xo,” “Eo,” and “x.” The user can obtain all parameters from Edge Gauging, Location Surveying, and Pedestal Detection directly from the sensor’s exit or via an OPTImess data proces­sing unit.


The two illustrations below demonstrate applications for weld seam scanning. In these applications, the OPTIscan’s / OPTImess 2D sensor exit is used for directing the welding robot. The OPTIscan / OPTImess 2D can simultaneously detect the center line of the welding groove, the groove’s depths, and the angle between the welding head and the primary material.


The examples outlined below illustrate another application where the position and orientation of parts need to be monitored during the assembling process (e.g., the positioning of dashboards or vehicle doors). The parameters “H” and “x” can be determined precisely in both cases.
