Hyperspectral Core Logger
Hyperspectral Core Logger
Using Corescan’s proprietary FTIR spectrometer design, the Hyperspectral Core Logger ( HCL ) integrates VNIR-SWIR-MWIR-LWIR spectroscopy, core photography and 3D laser profiling to deliver the most advanced, full range hyperspectral scanning system. The HCL system incorporates all sensors, an XYZ translation table, high speed data acquisition, data quality control and an advanced health monitoring and reporting system.
Corescan’s advanced optical and illumination design, focus’s the spectral measurement to a 10mm area on the core surface. Spectral measurements are acquired along the centre line of the core, collecting ~250 samples per metre at a scan rate of ~50mm per second. Co-registered photos and 3D laser profiler measurements are acquired simultaneously during the scanning process. Spectral calibration using NIST traceable standards is automatically managed by the system.
All sensors are housed within a 3-axis translation table that allows core trays, rock chips and other sample material to be handled automatically. An advanced system control module provides high speed data acquisition, quality control and system health monitoring. The HCL system is contained within a standard 20 foot, airconditioned sea container that serves as a mobile core-scanning and analysis laboratory allowing the system to operate in a range of remote environments.
