An illumination device for an image capture system according to one example embodiment includes an integrating light pipe having an input face and an output face. The integrating light pipe is positioned to receive light from a light source at the input face and transmit the light at the output face. A projection element is positioned to focus the light from the output face to a document plane to be imaged by an image sensor. A uniformity correction device is positioned to attenuate the light from the output face so that the light has a substantially uniform intensity at the image sensor and a less uniform intensity at the document plane than at the image sensor.

Illumination device for an image capture system

A user-wearable illumination assembly comprises a mounting fixture that is adapted to be coupled to a user-wearable device, such as eyeglasses, goggles, face masks, helmets, or other devices. A light guide has a first end that can be coupled to a light source, and a second end coupled to a lens housing that is in turn coupled to the mounting fixture. An optical lens in the lens housing cooperates with the light guide to project light from the light source through the lens. In one embodiment, the lens has a substantially spherical surface facing the second end of the light guide and an aspheric surface facing away from the second end of the light guide. In another embodiment, the mounting fixture comprises articulating portions to permit independent or simultaneous adjustment of the lens housing to direct projected light in a desired direction.

An optical system for use in projection based displays includes a plurality of solid state light sources associated with a plurality of total internal reflection based compound hyperbolic emitters, a graduated dichroic filter based device for homogenizing light output from the plurality of solid state light sources, a ferro-electric liquid crystal on silicon device for illumination with light output from the array of solid state light sources, and a polarization diffuser for homogenization of light at the ferro-electric liquid crystal on silicon device, wherein the polarization diffuser is positioned at a point in space, in the optical system, where the size of a beam of light transmitted from the graduated dichroic filter based device is substantially at a maximum.

A new and useful method and system for correcting for ghost images in a telecentric optical system is provided. Ghost images generated from planar optical surfaces in the image space after the major elements of a telecentric optical system are shift invariant. In other words the ghost images produced by these optical elements do not change their shape with different field angles or points. The ghost image's invariance with field position will allow the ghost image to be subtracted or removed from the image of an object recorded on a digital detector such as CCD or CMOS detector when its optical system is telecentric in image space. This subtraction may be accomplished, for example, with a removal technique using a measured ghost function germane and invariant to that particular optical system. The combination of the ghost image and scatter functions is linearly shift invariant and therefore, both noise contributions could be removed from the resulting digital image using similar removal techniques.

Ghost image correction system and method

A rear signal lamp of an automotive vehicle comprising a lamp housing and a curved cover lens for enclosing a thin light managing system. The thin light managing systems includes a plurality of backlight light-emitting diodes mounted in a light mounting substrate and secured to the lamp housing. A control module operatively connected to the light-emitting diodes for controlling the operation and illumination of the light-emitting diodes. A reflector matrix having a plurality of reflector cones corresponding to each of the light-emitting diodes in the mounting substrate and a hybrid optics panel having a direct lensing section covering the reflector matrix and light-emitting diodes and a double redirecting light pipe section surrounding the lensing section. A single light-emitting diodes is coupled along spaced apart quadrants of the redirecting light pipe. Each single light-emitting diodes emits light to the respective quadrant of the optics panel which is reflected and redirected from one or more lens facets to illuminated the front surface of the panel. The direct lensing section and redirecting light pipe illuminate distinct area on the curved cover lens.
