Background illumination and its effects on peripheral visual awareness for miners using cap lamps.
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.
