摘要： A position sensing device is disclosed wherein the positioning sensing device may determine the velocity and position of an object relative to a surface as the object is moved relative to the surface. The positioning sensing device may comprise two depth measurement devices that are mounted to the object on an axis that is substantially parallel to the direction of movement between object and the surface. The depth measurement devices are spaced a predetermined distance from each other. The depth measurement devices measure the contours of the surface as the object is moved relative to the surface and may output data representative of the surface contour to a processor. Accordingly, the processor receives two data signals that are out of phase wherein the phase shift is proportional to the relative velocity between the object and the surface. The processor may then perform an analysis on the data signals to determine the velocity of the object relative to the surface. Likewise, the processor may also determine the displacement of the object relative to the surface during a time interval.

摘要： An illumination system for illuminating a scan region on an object may comprise a hollow reflector having an interior reflective surface, an entrance aperture, and an exit aperture. A light source is positioned adjacent the entrance aperture of the hollow reflector so that some of the light rays produced by the light source pass through the entrance aperture and are reflected by the interior reflective surface of the hollow reflector before passing through the exit aperture.

摘要： A sensor assembly and an optical image color scanner using the sensor assembly. The sensor assembly is of the type having three separate rows of optical sensors. Two of the three sensor rows have color filters and one is unfiltered (receptive to white light). For gray scale scanning, only the unfiltered (white) sensor row is used, thereby maximizing the speed of gray scale scanning. For color scanning, three color values are computed as a linear transformation of values from the two filtered and one unfiltered values. The linear transformation may be as simple as subtracting signals from the two filtered sensor rows from the signal from the unfiltered (white) sensor row. For color scanning, memory buffers are required for two of the three sensor output signals. For highest accuracy in color scanning, the exposure time for the white sensor row is reduced relative to the exposure time for the two filtered sensor rows. An optional white channel bandpass filter (passing all wavelengths within the human visual range and rejecting wavelengths outside the human visual range) provides improved accuracy if the light source has significant wavelengths outside the human visual range.

摘要： In embodiments of imaging structure color conversion, an imaging structure includes a silicon backplane with a driver pad array. An embedded light source is formed on the driver pad array in an emitter material layer, and the embedded light source emits light in a first color. A conductive material layer over the embedded light source forms a p-n junction between the emitter material layer and the conductive material layer. A color conversion layer can then convert a portion of the first color to at least a second color. Further, micro lens optics can be implemented to direct the light that is emitted through the color conversion layer.

摘要： In embodiments of a folded imaging path camera, a device includes a camera lens module that focuses an image, which is received as reflected light. An image sensor captures the image from the reflected light that is directed at the image sensor. The device also includes one or more optics that fold the reflected light of the image along an imaging path directed through the camera lens module and directed at the image sensor. The imaging path directed through the camera lens module can be approximately perpendicular to an axis along which the reflected light of the image is received via an aperture in the device. Alternatively, the imaging path directed through the camera lens module is approximately parallel to the axis along which the reflected light of the image is received via the aperture in the device.

摘要： In embodiments of active reflective surfaces, an imaging structure includes a circuit control layer that controls pixel activation to emit light. A reflective layer of the imaging structure reflects input light from an illumination source. An active color conversion material that is formed on the reflective layer converts the input light to the emitted light. The active color conversion material can be implemented as a phosphorus material or quantum dot material that converts the input light to the emitted light, and in embodiments, the active color conversion material is laminated directly on the reflective layer.
