6.6.2. Laser Sensor

A Laser Sensor finds out whether the z direction of a laser marker passes target geometry or not. When the laser meets the target geometry, a distance from the starting point to the target geometry is measured. A rigid body, RFlex body and a FFlex body are available as the target geometry.

6.6.2.2. Properties

Figure 6.417 Laser Sensor property page

• Sensor Marker: Defines a sensor marker. The sensor marker’s position and the Z direction is used as the starting point and the direction of laser.

• Sensor Range: Defines the maximum range of laser. If the target geometry is met over the range, the result is neglected.

• Target Geometry: Defines the target of laser. When laser meets the target at first, the length from the laser to meeting position is returned as a result.

• Gr: choose a different Target Geometry.

• Data

  

  Figure 6.418 Target Surface dialog box

  • Plane Tolerance Factor: Specifies the surface tolerance factor as a value from 0 to 10. A smaller value produces a more refined patch. For more information, click here.

  • Max. Facet Size Factor: Specifies the max. facet size factor as a value from 0.01 to 10. This value controls the maximum size of triangular or quadrilateral patch length. Even though box geometry, if this value is defined (checked), box geometry can be used with lots of triangular or quadrilateral patches as shown in the below figure.

  • Add: Adds some of the target geometry.

  • Delete: Deletes some of the target geometry.

• Color: Defines the color of sensor icon.
