Before taking images make sure the lights and camera are calibrated properly. See section Light Array Setup and Camera Calibration for instructions on procedures.

Active Analyses
In MUT the 'active analyses' (Figure 14) should be set to Linescan Image, Processed RGB channels, and Whole-round Linescan. Linescan Image and Processed RGB Channels are for section half measurements. The Whole-Round Linescan Image is for 360 Imaging of hard rock cores. All three analyses should be set in the 'Active Uploaders' Column. Note it is ok for analyses to be in the 'Active Uploaders' even if MUT at that instrument host does not generate those files.

Auxillary data Produced
The SHIL has the capability to produce two additional file types at the scientist's request:
...
Hi RES RGB: This file default is turned off and can be turned on in Instruments > Camera: General Setup (FIG XXFigure 7). The Hi-Res RGB file reports a Red, Green, and Blue value for each line of pixels down the length of the core. 1cm is 200 lines of pixels so a 150cm core will yield approximately 30,000 lines of data depending on the exact crop length. The file is not currently uploaded to the database and is instead copied to data1 at the end of the expedition. The files can be put on the server for scientist access to a convenient, shared location such as UserVol.
VCD-S: The SHIL can preserve a digital copy of the VCD-S that is printed out. If a scientist wants to keep a digital copy of the scratch sheet turn on the feature in "XXXXXXXX" Instruments > Camera: VCDS Setup (Figure 15) . Files are then written to C: data > in > VCD-S. These files are not uploaded to LORE LIMS and should be put in data1 at the end of the expedition. The files can be put on the server for scientist access to a convenient, shared location such as Uservol.

The SHIL can be used to image the external surface of whole round hard rock cores in order to assemble a 360° composite image of the whole round. Oriented rock pieces are imaged after they have been binned and the structural scientist has marked the split lines on the pieces. Using the custom whole round scanning tray, the whole round core surface is imaged four times at the 0°, 90°, 180°, and 270° orientation from the splitting line. The Imaging Specialist will download the images and assemble a composite image from the four scans and upload the composite separately.
Sample Preparation
1. Remove the section half scanning tray from the SHIL and replace it with the whole round scanning tray making sure to align the blocks correctly. Note that the rotating section of the tray has 0°, 90°, 180°, and 270° markings on each end and that the rotating section will click and lock into each orientation.
2. Place the split liner section with the whole round core on the tray below the SHIL and align the top with the 0cm 0 cm on the ruler on the tray (Figure 16).
Figure 16. Whole round core correctly placed on the split liner section.
3. Remove the 0° aluminum strip and another aluminum strip on either side of 0°. Move the dry, oriented pieces into the tray, keeping the pieces at the correct offsets and aligning the split line with the 0° orientation.
4. Attach the not 0° aluminum strip and rotate the tray so that the 0° position is up, facing the camera (Figure 17).

Take Image
1. Click START and the Sample SHIL Section Information screen will appear (Figure 18).
2. Scan the section barcode from the endcap
3. Select the 360 Imaging type Imaging on Image Type and the default quadrant will be 0° 0 Degrees. Select Dry-Hard Rock. Click TAKE A PICTURE
Figure 18. SHIL Section Information window for 360 Hard Rock Imaging
4. When the scan is finished, the image cropping Image CROP window will open. Crop the image and Save it
5. The SHIL Section Information window for whole round rotation window will open and the rotation angle will default to the next quadrant, in this case , 90° 90 Degrees.
6. Replace the aluminum strip and rotate the tray to the next position, remove the aluminum strip facing up. Ensure that the rotation angle setting in the window is that same as on the tray. Click TAKE A PICTURE.
7. Continue the cropping, rotating and scanning process until all quadrants are complete. Once the images are uploaded to the database, the Imaging Specialist will create the 360 composite image and upload it to the database. If an image needs to be discarded, the software returns to the main screen and the user will need to start over, however, the user can select which quadrant to start on.
