20080245952 | Synchronous imaging using segmented illumination - In an actively illuminated imaging system, illumination of a segmented scene is synchronized with an image sensing period. A scene is segmented into a plurality of scene portions utilizing a segmented lens. In an aspect, a first scene portion is illuminated when an imager is actively collecting photogenerated charge from the first scene portion, and a second scene portion is illuminated when an imager is actively collecting photogenerated charge from the second scene portion. The sensitivity of an image sensor is maximized, while simultaneously minimizing the amount of light that must be supplied to illuminate a scene. An irradiance pattern is varied allowing a more uniform distribution of light. Bands of varying wavelength, polarization, and light intensity may be variously applied to illuminate individual scene segments, as needed to enhance an identification of an object in the scene. The present invention is particularly useful with high frame rate imaging systems. | 10-09-2008 |
20100200737 | Optical system for controlling light propagation along a light path - An optical system and method for controlling light propagation along a light path. An optical element such as a lens is formed of a first light transmitting material and has a surface finish effective to scatter light impinging on the surface. Index matching material contacts to a portion of the surface so as to reduce or nullify the scattering effects of the surface finish within the portion. This allows the first optical element to have surfaces that have been generally prepared for scattering light and then later selectively negate the scattering effects of the surface finish by contacting portions of the surface with index matching material. As such, light in the optical element directed toward a surface or boundary within selected portion propagates into or out of the optical element. Light outside of the selected portion is scattered. Such an arrangement helps to reduce image degradation due to light outside of the light path being reflected about within the optical system. | 08-12-2010 |
