Definitions

  • the golf balls have covers that include a fluorescent material that produces fluorescence in a spectral region corresponding to a spectral transmittance of a viewing filter.
  • a portion of the object- contrast window corresponds to a spectral region in which light is preferentially reflected by the cover.
  • Table 1 Spectral transmittance of a filter configured for viewing a golf ball in daylight illumination.
  • the green window 204 has a maximum spectral transmittance at a wavelength of about 550 nm. Because vegetation typically appears green, the green window brightens portions of a scene that include vegetation.
  • FIG. 3 illustrates the spectral absorptions of chlorophyll a and chlorophyll b that contribute to vegetation appearance. As shown in FIG. 3, both chlorophyll a and chlorophyll b are relatively reflective at wavelengths between about 500 nm and 600 nm. Without the green window 204, light at wavelengths between 500 nm and 600 nm is blocked or attenuated, and vegetation would appear relatively dark.
  • the red window 206 extends over a wavelength range from about 610 nm to about 720 nm, but the transmission of radiation at wavelengths beyond about 700 nm provides only a small contribution to a viewed scene because of the low sensitivity of the human eye at these wavelengths.
  • the red window 206 enhances the natural appearance of scenery viewed with an optical filter having a spectral transmittance corresponding to FIG. 2 A, transmitting some red light reflected by vegetation, and provides additional advantages by improving the golfer's ability to focus more accurately. Because the ability of the human vision system to focus is proportional to the spectral bandwidth of the radiation received by the eyes, the more polychromatic light produced by transmitting red, green, and blue components of light permits improved focus.
  • spectrally transmitting windows in the green and red portions of the spectrum permits improved depth perception as well as improved focus.
  • a filter having such spectral windows provides improved perception of vegetation (especially putting surfaces) as well as providing more natural looking scenery while retaining the enhanced golf ball visibility associated with the blue window.
  • dilation of the golfer's pupil is reduced, further improving the golfer's ability to see objects accurately.
  • spectral windows can be chosen based on expected or measured background colors and wavelengths produced by a wavelength-conversion process. For example, tennis is often played on a green playing surface with an optic yellow ball. Such a ball typically has a wavelength conversion region that produces wavelength- converted light at wavelengths between about 460 nm and 540 nm.
  • An example filter for such an application has a wavelength-conversion window at between 460- 540 nm, and a background window centered at about 550 nm.
  • the wavelength- conversion window and the background window can have some overlap.
  • additional transmission windows can be provided in wavelength ranges of about 440-460 nm, 620-700 nm, or in other ranges.
  • Background windows and spectral- width windows are then provided so that backgrounds are apparent, scenes appear natural, and the wearer's focus and depth perception are improved.
  • different background windows can be provided for play on different surfaces.
  • tennis is commonly played on grass courts or clay courts, and filters can be configured for each surface, if desired.
  • ice hockey can be played on an ice surface that is provided with a wavelength-conversion agent or colorant and lenses configured for viewing a hockey puck with respect to such ice.
  • Outdoor volleyball requires accurate viewing of a volleyball against a blue sky, and the background filter can be selected to permit accurate background viewing while enhancing contrast in outdoor lighting.
  • a different configuration can be provided for indoor volleyball.

Abstract

L'invention concerne un dispositif optique comprenant des lentilles à transmittances spectrales sélectionnées pour visualiser un objet par rapport à un fond. Les transmittances spectrales sont sélectionnées pour donner une dimension naturelle aux scènes visualisées à l'aide du dispositif optique. Dans un exemple, une lentille de visualisation d'une balle de golf blanche comprend une fenêtre spectrale de contraste avec l'objet qui transmet des rayonnements à des longueurs d'onde d'environ 440 nm, une fenêtre de fond qui transmet des longueurs d'onde à environ 550 nm, et une fenêtre de largeur spectrale qui transmet des longueurs d'onde entre environ 620 nm et 700 nm. Des dispositifs optiques semblables peuvent être configurés pour d'autres activités. L'invention concerne également des procédés de sélection de filtres et de lentilles pour de tels dispositif optiques.
