Abstract:
A light source having a first mixing chamber, a light pipe structure, and a controller is disclosed. The first mixing chamber includes a first plurality of LEDs, the first mixing chamber having a first transparent window through which light from the first plurality of LEDs exits the first mixing chamber. The light pipe structure has a first end optically coupled to the window such that light from the first plurality of LEDs enters the first end and a second end through which the light exits. The controller determines the power that is applied to the first plurality of LEDs and includes a photodetector optically coupled to the second end of the light pipe structure. The photodetector generates signals indicative of an intensity of light generated by the LEDs, the controller causing the LEDs to be powered such that the signal matches a target value.
Abstract:
A method for providing a hot spot filter for a light guide is provided by taking an image of the light output pattern of an illuminated light guide. The hot spot filter may be a film, a layer, or an additional liquid crystal display dedicated to attenuating bright spots from the light guide. The hot spot filter may be incorporated into the image display by adjusting the grey scale of individual pixels to provide sufficient compensation.
Abstract:
Exemplary embodiments can be used in a replicating system to guide source electromagnetic waves, such as infrared (IR) radiation, from an emitter of a reflective-type sensor towards an object held on a support mechanism and to guide reflected electromagnetic waves that are related to the source electromagnetic waves to a receiver of the reflective-type sensor. The height of the support mechanism can be adjusted based on whether the object is detected.
Abstract:
An optical sensor device for detecting ambient light is adapted to be coupled to a pane (10), in particular to a windshield of a motor vehicle. The optical sensor device has a sensor unit which includes at least one light receiver (26) and a lens plate (12). By means of the sensor unit, an ambient light beam having entered the pane (10) is coupled out of the pane (10) and directed onto the light receiver (26). On a surface (12b) which faces the pane (10), the lens plate (12) includes a first Fresnel prism structure (22) having a plurality of individual structures (24). The individual structures (24) of the first Fresnel prism structure (22) are designed such that they deflect the light beam at different angles.
Abstract:
A hand-held probe for intra-operative detection of fluorescence labeled compounds includes a housing comprising a handle and a columnar portion, and a power source within the housing. A light emission source proximate the columnar portion of the housing is configured to fluoresce at least one of predetermined compounds and predetermined antibodies. An excitation switch proximate the handle selectably activates the light emission source. A detector receives fluorescent light emissions directed toward the columnar portion from at least one of the compounds and antibodies and convert the fluorescent light emissions to a corresponding emission electrical signal. A controller within the housing receives the emission electrical signal from the detector and converts the emission electrical signal to a corresponding data signal. Finally, a data port within the housing receives the data signal from the controller, converts the data signal to a corresponding output signal, and transmits the output signal.
Abstract:
The optical source assembly/solar simulator comprises a light source, and a reflector for collecting the light and directing the light in a desired direction. In certain embodiments a spectral filter assembly receives the light from the reflector and blocks at least some of the light at specific wavelengths to produce filtered light. The spectral filter assembly is quickly and easily adjustable to vary the spectral spread of the light in the output beam. A homogenizer receives the filtered light and produces a homogenized beam having a substantially uniform irradiance distribution across the beam's cross-section and a substantially uniform spectral distribution across the beam's cross-section. In certain embodiments, a lens assembly images and sizes the homogenized beam at a point in space where a device to be tested can be placed.
Abstract:
A light source control apparatus that includes a light quantity detection unit that respectively detects light quantities of three colors of light emitted from a light source part. A light quantity ratio calculation unit that then calculates light quantity ratios of reflection light detected by the light quantity detection unit. When the light quantity detection unit detects light quantities of respective reference of the lights emitted from the light source part, a determination unit determines whether or not the light quantity ratios calculated by the light quantity ratio calculation unit are within a predetermined range. Responsive to the determination of the determining unit, a light quantity ratio adjustment unit adjusts the light quantity ratios of the lights emitted from the light source part on the basis of the light quantity of green-colored reflection light emitted from the light source part.
