title: Background illumination and its effects on peripheral visual awareness for miners using cap lamps.
abstract: The effects on the detection of objects moving in the peripheral field of adding ambient illumination (giving an illuminance of 5 lux) to that provided by a miner's cap lamp were examined in simulated underground conditions. The results indicated that an object moving into the visual field was detected at a significantly wider angle with the 5 lux ambient illuminance than without it and that greater target reflectance also increased the range of peripheral vision.
