Hyperspectral Core Imaging
Using Corescan’s proprietary imaging spectrometer design, HyImager integrates high resolution VNIR-SWIR imaging spectroscopy, core photography and 3D laser profiling to deliver the most advanced automated core logging system. The HyImager 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 measurements at 250μm pixels to create an image of the core surface. Hyperspectral images are acquired along the core surface collecting ~800,000 samples per metre at a scan rate of ~35mm 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. HyImager 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.
