ABSTRACT:
A macroscopic and microscopic video record of whole core is stored by translating the core in increments adjacent a video recording station. The core is stopped and movement damped prior to storing the video record for each increment. Overlapping or contiguous macroviews are made using a video camera and in the center of each macroview a microview is also video recorded. The video records are stored in a random access video memory and are retrievable by depth. Macro and microviews of any depth can be instantaneously retrieved and viewed and scanning up or down by depth is also possible.
