The High Resolution Optical Televiewer (Hi-OPTV) provides a continuous very high resolution oriented image of the borehole walls using a
conventional light source. A unique optical system based on a fisheye lens allows the probe to survey 360 degrees simultaneously. This
information is processed in real time to produce a complete ‘unwrapped’ image of the borehole oriented to magnetic north. The probe offers
superior resolution to the High Resolution Acoustic Televiewer (HRAT) and produces images in real colour. While, unlike the HRAT, it can
operate in air-filled boreholes, it is unsuitable for boreholes containing mud or cloudy fluids.
