    2.2 C-ALS Carlson’s C-ALS is tubular in design and has a diameter of just 50 mm. This allows the instrument to be deployable into voids via drilled boreholes. The C-ALS can be deployed up to 200m before being secured in place to scan a void it has entered.

    Alternatively, if you are independently selecting a Windows-based tablet or laptop to run Carlson Scan, consider the following points when making your choice. Carlson Scan Tablet mode is optimized for use on a touch screen tablet with a screen size of around 10.1”, although it will run on smaller screen sizes if required.

  • Page 10: Software Installation

    Carlson Scan has a non-restrictive distribution license, so it may be installed on as many tablets as required. If you ordered a rugged tablet from Carlson as part of a C-ALS purchase, Carlson Scan is already loaded on the tablet.

    Carlson downloads page Note that the legacy version 1.3.6 is also available from this page. Carlson Scan version 1.3.6 is the last version that works with C-ALS Mk3 and Void Scanner units. At the bottom of the download page enter your name and email address and click Update. You will be sent an email notification whenever a new version of Carlson Scan is released.
  • Page 12 3.5 Data storage and file formats A Carlson Scan project is saved as an *.NDV file. You can open this file from within Carlson Scan by using the Open function. Alternatively, double-click on the file in Windows Explorer to automatically open the selected project inside Carlson Scan.

  • Page 13: Viewing Modes

    3.6 Viewing modes Carlson Scan is designed to be used with a choice of two viewing modes: Tablet and Desktop. The mode can be selected when starting up the software. A Desktop button is available on the Tablet mode Home screen (section 4.9).

  • Page 72: Control Tab - Vs

    Carlson Scan first identifies that a VS+ is connected (or a C-ALS if that is the scanner you are using – see section 11.1) and then establishes the serial number, firmware and internal sensors within the instrument.
  • Page 73 Prior to initiating the autodetect routine, you may have used the standard Windows tools to connect to a Wi-Fi device such as the VS+. This allows the autodetect routine to find the scanner. However, you can also connect to a Wi-Fi device from within Carlson Scan. Prior to using the Find Scanners button, tap the Wi-Fi button.
  • Page 74 10.1.3 Connected On detection of a scanner, Carlson Scan runs through checks to establish that comms with the scanner are sound and to read information from the scanner. With all checks complete, a graphic of the VS+ appears in the 3D View.

In this case, the deployment controls appear slightly different (see section 11.8).
  • Page 95 The results from the circle scan help to establish if there is enough space around the laser head for the C-ALS to conduct a full scan with the full range of vertical rotation. It is safer to use a circle scan to perform this check as the head will not move vertically and thus, even if the probe is still in the borehole and has not yet emerged into the void, it will not jam against the adjacent rock.

    The particles may be water vapour or dust in the air which may cause the laser pulse to reflect back to the instrument before it hits the intended target. Activating this mode will instruct the C-ALS to attempt to ignore any interference from the particles in the air and instead to concentrate on returns from the true target.

    C-ALS probe on power up is completely different to that of the ambient temperature in the deployment area. In this case, for optimum results, you may wish to leave the C-ALS switched on for a period of 10 to 20 minutes prior to a deployment to allow the internal temperature to stabilise.
  • Page 117 15.1.3 Reference azimuth The gyro in the C-ALS does not output an azimuth with respect to true north. The gyro can measure the angle that it is rotated through as it is deployed or as it is moved around on the surface, but it cannot determine which direction it is pointing in when it is switched on.
  • Page 118 During the deployment, lower the probe carefully and steadily. Using rods to deploy the C-ALS helps to ensure that the probe cannot twist at all. If you do deploy on the cable alone, try to ensure as little rotation as possible is introduced through twist in the cable.
  • Page 119 If the C-ALS is deployed down a borehole, then the scan head and the rotating horizontal shaft must be free of the hole to allow unrestricted motion. However, the probe must not be deployed so far that its full length flops out of the borehole.

Prior to deployment of the C-ALS, check the area in which the deployment will take place. Consider: What is the level of accessibility at the site for personnel and vehicles? •...
  • Page 121 However, if the alignment jig is being used for a vertical alignment at the top of the borehole, the reference azimuth must be established at the time of the C-ALS alignment, as the alignment jig must be moved as soon as the deployment commences.

    In these cases case, for optimum results, you may wish to leave the C-ALS switched on for a period of 10 to 20 minutes prior to a deployment to allow the internal temperature to stabilise.
  • Page 123 Do not switch the C-ALS system off between starting the warm-up period and starting the deployment. When the C-ALS is first switched on, and when it is located in position to carry out the alignment, the C-ALS should be in a state that is ready to deploy without powering down.
  • Page 124 All gyro readings thereafter will be related back to this aligned heading. If you are aligning the C-ALS probe horizontally, survey the heading of the probe from the end of the extension piece to the laser head. If appropriate, the jig can be left in place for the duration of an operation and, once the heading has been surveyed, and as long as the jig is not moved, the same heading value can be used for multiple deployments.
