  • Page 2: Overview

    1 Overview This application note describes how to set up and use the Gocator’s built-in support for dual-sensor operation. The document is divided into two main parts. The first part is based on the user manual for all the basic setup steps, whereas the second part describes in detail how to align the system into a common coordinate frame and briefly explains how measurement tools can be used on the combined data.

  • Page 3: System Layouts

    Figure 1: Gocator 2300 Family Connection (Master 2400 pictured) 3.2 System Layouts The examples below illustrate the possible mounting layouts for dual-sensor systems. The mounting relationships between the Main and the Buddy sensor must be as shown in the following diagrams. When viewed from the rear, in Wide and Reverse layout, the Main sensor is always on the left.
  • Page 4 addresses before they can be used on the same network. Before proceeding with these instructions, connect the Main and Buddy sensors one at a time (to avoid an address conflict) and follow the steps below. 1. Turn off the sensors and unplug the Ethernet network connection of the Main sensor.
  • Page 5 6. Change the IP address to 192.168.1.11 in the Network settings and click the Save button. When you click the Save button, you will be prompted to confirm your selection. 7. Turn off the sensors, re-connect the Main sensor’s Ethernet connection and power-cycle the sensors.
  • Page 6 10. Go to the Sensor System category on the Manage page. The serial number of the Buddy sensor is listed in the Visible Sensors area. 11. Select a sensor to assign as the Buddy and click the Assign button. The Buddy sensor will be assigned to the Main sensor, and its status will be updated in the System panel.

    single profile. 15. Move a target into the laser plane. If a target object is within the sensor’s measurement range, the data viewer will display the profile of the target and the sensor’s Range indicator LED will illuminate. In the data viewer’s drop-down box, select Left &...
  • Page 8 Figure 5: Alignment bar specifications Figure 6 shows two Gocator 2330 sensors mounted side by side in a Wide layout, with an alignment bar in their field of view (FOV). In this case the sensors are close together and their individual FOV’s are physically overlapping, which is suitable in applications where high resolution is required to scan a target that is larger than the FOV of a single sensor.
  • Page 9 Figure 7 shows what the unaligned profile data looks like in the data viewer. Note again that Left & Right must be selected in the data viewer’s drop-down selection box. Figure 7: Unaligned profiles from both the Main and the Buddy Alignment of the Gocator is done in the Alignment panel on the Scan page.
  • Page 10  The correct layout must be selected in the Layout section in the Sensor System category on the Manage page before alignment for a successful operation. See Figure 9.  If the Main and Buddy sensors are mounted so that the camera from one sensor can detect the laser from the other sensor, the Exposure Multiplexing feature can be used to eliminate laser interference.
  • Page 11 After successful alignment, the profile data from the two sensors should resemble Figure 10. Figure 10: Successful alignment Measurement tools can now be applied to the system-aligned data for dimensionally correct results across the combined field of view, as shown in Figure 11.

  • Page 12: Dual-Sensor Mounting Layouts And Orientations

    5 Dual-Sensor Mounting Layouts and Orientations There are a number of possible dual-sensor layouts and orientations. These configurations are set up and aligned in the same way as the example, with the exception that sometimes only a single reference hole is needed for alignment.
  • Page 13  Opposite layout – used to measure true thickness of a target. The Exposure Multiplexing setting should be disabled so that the two sensors capture data at the same time. The two sensor’s lasers should be aligned to form a single plane. Alignment is performed using a bar with a single hole, as illustrated below.
