Sensor technology available for this platform:
• Olympus Vanta pXRF
• 5K Geoscan V Linescan camera (UV and VIS Light)
• Bartington Point Magnetic Susceptibility meter
• 3D Laser Profiler
The Geotek Geoscan V line scan camera has one massive c.5340 pixel CCD. Incoming light is passed through a set of red, green, and blue filters to produce true independent colour separation. Averaged image data can be converted to these RGB values and saved in a separate file to facilitate quantitative comparisons between cores and other down-core measurements.
Single lines of image data are collected sequentially down the core. Line-scan images are far superior to area camera images because they do not suffer from uneven lighting, spherical distortion, montage or “stitching” effects. The entire image is suitable for calibrated sub-millimetre image analyses.
Images can be collected over the full core width between 100 and 1000 lines per centimetre, corresponding to 100 and 10 micron pixel sizes, respectively. Images are output as 48-bit RGB TIFF images but are quickly and easily converted to JPEG or other formats as required. Each Geotek core section image has a companion XML metadata file, containing important metadata pertaining to the core section and imaging conditions. A ruler can be generated next to the image, depicting either depth in core section or depth in core.
The camera is factory-calibrated and a standard photographic 18% grey, or 90% white cards are used for field calibration, enabling images to be qualitatively or quantitatively compared to each other.
Advanced Camera Control
The Geoscan V has automatic focus, aperture and light control routines built in to the Geotek imaging software. The software now guides the user through the camera and lighting set-up to optimise image exposure consistently and simply.
Three Minutes per Metre is normal scan time for standard (50 micron) resolution,for the higher resolutions time increases.
Co-location of analytical data points displayed in a waterfall plot – Gamma/Bulk Density, P-wave velocity, Fractional porosity, Uniaxial Compressive Strength impedance, Magnetic Susceptibility, Electrical Resistivity, Natural Gamma, MgCa/AlSi ratio, Ca concentration, Si concentration (plots shown are for illustration purpose only)
The Boxscan has been ruggedly designed for field work and can incorporate your existing pXRF. It has multiple sensors including magnetic susceptibility, XRF and laser profiler to measure α and β angles. These datasets are depth-correlated with high resolution true colour dry core images and cross-polarisation for wet core photography.
