ABSTRACT:
Presented is a method and apparatus for providing human visual physiology with a perceived continuous image of a fast-moving object formed by a series of visual pulses each followed by a period of visual blockage where the frequency of these repetitive pulses/blockages is selectively adjusted to be close to the actual flicker fusion frequency of the observer at the perceived brightness of the visual pulses. The objective of this method is to provide the observer with enhanced visual. perception of fast-moving objects. The method and apparatus presented is intended for use under natural lighting conditions and continuous artificial lighting conditions and is accomplished by spectacles with optical shutter lenses. The lenses are alternately opened to provide the wearer with an unhampered view of the surroundings and then closed to block out the view and as much light transmissibility as possible. The optical shutter lenses operate near the flicker fusion frequency of the wearer to ideally provide only one image in each visual frame of the viewer and in actual, practice to provide as few double image frames as possible.
