Abstract
An optical scanning system. In representative embodiments, an optical scanning system is disclosed which comprises at least one first photosensitive detector that is sensitive to light in a first frequency band, an exposure control circuit that is capable of exposing the first photosensitive detector for a first time period and at least one second photosensitive detector that is sensitive to light in a second frequency band. The second photosensitive detector is fixed at a first location relative to the first photosensitive detector. The exposure control circuit is capable of exposing the second photosensitive detector for a second time period with the second time period being longer than the first time period and the midpoint of the first time period occurring at a time proximate to the time of the midpoint of the second time period.
