摘要： A light source having first and second phosphor-converted component light sources is disclosed. The first component light source includes a first LED that emits light at a first wavelength and a first luminescent conversion material layer that converts light of the first wavelength to light of a first output wavelength, and the second component light source includes a second LED that emits light at a second wavelength and a second luminescent conversion material layer that converts light of the second wavelength to light of a second output wavelength that is different from the first output wavelength. The first and second LEDs are constructed in the same material system, preferably in the same batch of wafers on the fabrication line. A controller generates a current through each of the first and second LEDs that results in the light source generating light that is perceived to be a predetermined color.

摘要： An apparatus including an image sensor is disclosed. The apparatus includes a polarization filter, an image sensor, and a processor connected to the image sensor. The polarization filter is adapted to filter out light polarized in a first direction from a first scene. The image sensor is adapted to capture the filtered light, and the image sensor includes support circuits to convert the captured filtered light to image data. The processor is adapted to process the image data to detect features of the first scene. The polarization filter filters out noise component of the image, thus increasing contrast. In another embodiment, a mosaic polarization filter is used to capture a scene in a first image including light from the scene having first polarity and to capture the scene in a second image including light from the scene having first polarity. The two images can be analyzed to determine various characteristics of the scene.

Specifically, the optical navigation device includes a light source that is configured to illuminate a reflective surface through a layer that is optically transparent to the light source. A sensor is configured to generate navigation information in response to light reflecting off the reflective surface. The sensor is configured with a depth of field to support a distance between the sensor and the reflective surface. A contact sensor is also included to indicate when the optical navigation device is no longer in contact with the transparent layer. The contact sensor allows for skating functionality for the optical navigation device.
