    摘要： The present invention provides an optical system having an array of light emitting semiconductor devices to performing an operation that have multiple characteristics associated with performing the operation. The array includes at least one detector located within the array to selectively monitor multiple characteristics of the light emitting semiconductor devices and is configured to generate a signal corresponding to the selected characteristic. A controller is configured to control the light emitting semiconductor devices in response to the signal from the at least one detector. At least one of the multiple characteristics may be concentrated at an area of the array and the at least one detector may be located within the array at the area of the array to selectively monitor characteristic that is concentrated at the area of the array.

    摘要： An array of LEDs (30) is provided having a lens array (34) for collecting divergent light from each LED (30). Each lens (34) in the array is associated with a respective LED (30) and has a compound shape including a curved surface (40) that may be spherical or may have an offset aspherical shape. The curved surfaces (40) are centered about each side of its associated LED (30). The lens (34) may alternatively include faceted surfaces (46) that approximate the curved lens surface.

    摘要： A spatially distributed sensor system has an optical transmitter, an optical conduit optically coupled to the optical transmitter at an input position, and a sensing element optically coupled to the optical conduit at a position along the optical conduit spatially separated from the input position. The sensing element is structured to split off a fraction of light from the optical transmitter upon being coupled into the optical conduit and to return light to the optical conduit. The spatially distributed sensor system also has an optical receiver coupled to the optical conduit to receive at least a portion of light from the optical conduit that includes light returned to the optical conduit from the sensing element. An analysis of light received by the optical receiver provides information to determine a position of the sensing element.

    摘要： An optical detection system includes an optical transmit-receive system, an optical conduit in optical communication with the optical transmit-receive system, and an optical sensor in optical communication with the optical conduit. The optical transmit-receive system provides pulsed optical signals to the optical sensor by way of the optical conduit that have a maximum pulse width of about 100 nanoseconds and further have a maximum pulse width that is less than a maximum distance of reflection of the pulsed optical signals in the optical detection system to decrease false alarms.
