Abstract
An adaptive lighting system for even illumination is provided. In an embodiment, multiple lamps illuminate light in different areas or zones of the surroundings. These lamps modulate their light output in a known (but imperceptible) pattern. One or more light detectors detects light from the surroundings. Light sourced from each lamp is disambiguated and one or more light time-of-flight delays are calculated for each lamp-light detector pair. Based on these calculated delays, illumination levels of the lights are adjusted so as to produce even illumination.
