    You can collect grids of three preset sizes: 1x1, 2x2, and 2x4 feet (30x30, 60x60, and 60x120 cm). You can use one of the paper scan pads supplied by GSSI as a template, create your own, or even draw a grid on the survey surface. If you create your own or draw a grid, it must be one of the three preset sizes and the grid lines must be 2”...

  • Page 20: Setting Up Collection Parameters

    Dielectric: Setting this correctly results in a more accurate depth reading on your objects as well as a cleaner 3D image. Please see Appendix A for details on setting the dielectric. GSSI recommends using one of the tools available in ScanMax to accurately gauge your dielectric so that you can enter that value during 3D setup.
  • Page 21 StructureScan Mini XT Quick Start Guide Page 17 Collecting a Grid Lasers properly aligned Position the Mini XT on the first line in the “X” direction on the scan template. Take care that the side lasers are lined up on the thick, black start line and that the front laser is aligned with the line you are scanning.

  • Page 24 StructureScan Mini XT Quick Start Guide Page 20 Analyzing 3D Data The menu carousel will have the following options once the grid displays: Slicing Cursor: Toggle the crosshairs On/Off. Position: Selecting this option will allow you to use the Up/Down keypad arrows instead of running your finger along the Slicing Bar to change your slice position.
  • Page 25 This should not be considered as a definitive answer, but rather as an interpretive tool. Do not rely solely on this feature for your interpretations. Please refer to the StructureScan Mini XT manual for details. Slicing To slice through the data, select a viewpoint which shows a clear image of the horizontal plane.
  • Page 26 StructureScan Mini XT Quick Start Guide Page 22 Refining the Image The grid data are being processed with a technique called “migration.” Migration will remove the tails from the hyperbolas and collapse them back to the target’s central point. It is very useful as a tool for tightening up the 3D image.

  • Page 28: Appendix A: The Dielectric Constant

    StructureScan Mini XT Quick Start Guide Page 24 Appendix A: The Dielectric Constant. What is it? The dielectric constant is number used in GPR to describe how fast the GPR energy moves through a non- metallic material. GPR waves move so fast (almost the speed of light) that it is not practical in most cases to use familiar units like miles or kilometers per hour, so we use the dielectric as an easier method.

  • Page 29: Appendix B: Data Interpretation And Examples Of Common Features

    StructureScan Mini XT Quick Start Guide Page 25 Appendix B: Data Interpretation and Examples of Common Features This section presents some data images of some common targets. While the GPR cannot differentiate different types of metal (rebar vs. metal conduit vs. post-tensioned cables) on the basis of the signal alone, the depth, spacing, and direction of the object often gives us clues as to its identification.
  • Page 30 StructureScan Mini XT Quick Start Guide Page 26 Potential Void under Slab This image shows a wire mesh reinforced slab. Note the heavy black band below the wire mesh and shown by the orange arrows. The black band results from a pronounced high to low dielectric change as in concrete to air.
  • Page 31 StructureScan Mini XT Quick Start Guide Page 27 Rebar This image is of #8 (1” diameter) rebar spaced 12” (30 cm) apart. Compare this image to the previous two examples. Notice that while there is a constant spacing, the spacing is too wide for normal wire mesh.
  • Page 32 StructureScan Mini XT Quick Start Guide Page 28 Empty PVC Conduit The hyperbola identified by the orange arrow is an empty PVC conduit above a row of rebar. Note that the dominate color for the PVC hyperbola is black while the rebar is white.
  • Page 33 StructureScan Mini XT Quick Start Guide Page 29 Cinder Block/CMU Filled cell The Mini XT is an effective tool for non-destructively checking for proper CMU construction. The data at the right was collected by running the Mini XT horizontally along a course of CMUs.
