  • Pattern illumination device
    Patent number: 5988815
    Abstract: An apparatus for illuminating a portion of a patient's body includes an enclosure having a generally smoothly curved shape, an internal light-scattering surface, and an opening. A light source provides light to a portion of the light-scattering surface within the enclosure so as to illuminate the surface via scattering of the light on the surface. An at least partially transparent member is positioned within the enclosure so that scattered light passes through it and through the opening.
