摘要： A light source assembly and method of providing illumination a target surface utilize a fluorescent material to generate composite "white" light from source light of a particular color, i.e., a particular wavelength. The light source assembly is optimally designed for use in scanning devices, such as flat-bed color scanners, in which linear illumination is necessary to capture images, graphics, and/or text from a target scanned surface. In the preferred embodiment, the light source assembly includes a Gallium Nitride (GaN) based light emitting diode (LED) that emits blue source light and a light transmitting rod lens. The light transmitting rod lens is preferably a solid transparent structure, designed to receive the blue source light through one end of the rod and transmit a composite "white" light from the entire length of the rod, providing the desired linear illumination. The rod lens includes two fluorescent strips and a non-fluorescent strip, located near the exterior surface of the rod. The two fluorescent strips operate to absorb the blue source light and to emit red light and green light, while the non-fluorescent strip reflects the blue source light. The emitted red and green light, along with the reflected blue light, form the composite light that provides the linear illumination on the target surface.

摘要： A ferroelectric liquid crystal-based display device comprising a light source, a reflective spatial light modulator, a light output, a beam splitter, and a shutter. The beam splitter is located and aligned relative to the light source, the light output, and the spatial light modulator such that light generated by the light source is reflected or transmitted towards the spatial light modulator, and then light reflected by the spatial light modulator is reflected or transmitted towards the light output. The shutter has both and OPEN and a CLOSED state, and may include ferroelectric liquid crystal material. The shutter may be located and aligned relative to the lights source and the beam splitter such that when OPEN it transmits the light generated by the light source towards the beam splitter, and when CLOSED it prevents transmission of the light generated by the light source towards the beam splitter. Alternatively, the shutter may be located and aligned relative to the light output and the beam splitter such that when OPEN it transmits the light reflected by the spatial light modulator towards the light output, and when CLOSED it prevents transmission of the light reflected by the spatial light modulator towards the light output. A color separator and a first, second and third reflective spatial light modulators may be used in place of the above-described spatial light modulator. The color separator is located and aligned such that a first, second, and third wavelength band from the light generated by the light source, after being transmitted or reflected by the beam splitter, is transmitted or reflected towards the first, second, and third reflective spatial light modulators, respectively. Each of the first, second, and third reflective spatial light modulators include ferroelectric liquid crystal material.

摘要： A camera provides an autofocus function by capturing a series of images when a lens is at different positions, analyzing the images to identify a best-focused image, and outputting the best-focused image. Unselected images can be discarded. The camera can include a FIFO buffer that receives image data from an image sensor as the image sensor captures images. When a photographer activates a shutter button, an analysis system, which may be implemented in software, analyzes the images in the FIFO buffer and selects the best-focused image for output. In alternative embodiments, the movement of the lens and the capture of the images can be before or in response to activation of the shutter button.

摘要： A lens system has an optical path through a lens that is in contact with a liquid. The focal length of the lens system can be changed through introduction of a bubble in the optical path at the lens-liquid interface. The bubble changes the refractive index difference at the lens surface and thereby changes the focal length of the lens system. In a camera, the lens system can operate in a macro mode corresponding to a shorter focal length or a normal mode corresponding to a longer focal length.

摘要： An optical display system includes a light source, a color wheel, an optical train and a light valve. The optical train includes a diffuser element, a compound parabolic concentrator and an integrator. The diffuser element diffuses incoming light to fill in holes in cone half-angle distribution of light generated by the light source. The compound parabolic concentrator reduces the cone half-angle of the diffused light to a cone half-angle expected by the light valve. The integrator reduces hot spots in the diffused light. The color wheel may modulate optical path length of light traveling through the color wheel. Modulating the optical path length reduces coherence in the light generated by the light source. A color wheel that reduces coherence would allow the light source to be laser or LED-based. If the light valve is a ferroelectric light valve, the color wheel may include pairs of polarizers. Light is polarized in orthogonal directions by the polarizers in a pair. This allows all of the light to be used by the ferroelectric light valve during dc balancing.

摘要： A light source used to measure color involves associating a light emitter that emits light having a first spectral distribution with a wavelength-shifting medium that absorbs the emitted light and re-emits the light at a second spectral distribution that approximates one of the three color curves of the CIE standard X, Y, and Z tristimulus functions. Preferably, the light source involves associating known blue light sources with a green-converting lens and a red-converting lens where materials integrated into the lenses, preferably fluorescent organic dyes, absorb the blue light and re-emit green and red light respectively. The blue light, the converted green light, and the converted red light, are generated to closely match the CIE standard X, Y, and Z tristimulus functions in order to measure color in a manner that correlates to the color sensitivity of the human eye. The blue light used to generate the blue, green, and red light is preferably generated from Galium Nitride based LEDs that are encased in epoxy lenses. The flourescent organic dyes used to create the green and red light are mixed into the epoxy lenses that encapsulate the respective blue light emitting LEDs.
