    • A color-corrected lighting system for night vision applications includes a near infrared light source and a thin-sheet optical element disposed a distance from the near infrared source. The optical element includes an input surface for receiving light from the near infrared source and an output surface for emitting the received light in a desired emission pattern. The system also includes a visible, non-red light source in the form of a plate having a plurality of non-red LEDs arranged thereon. The plate is proximate a surface of the optical element such that the output surface of the optical element emits the visible light to mask the emitted near infrared light. A camera is adapted to receive the near infrared light from the near infrared light source reflected off an object within a camera field of view, and a display images objects detected within the camera field of view.
    • 用于夜视应用的彩色校正照明系统包括近红外光源和与近红外光源相距一定距离的薄片光学元件。 光学元件包括用于接收来自近红外源的光的输入表面和用于以期望的发射图案发射所接收的光的输出表面。 该系统还包括具有布置在其上的多个非红色LED的板形式的可见非红色光源。 板靠近光学元件的表面,使得光学元件的输出表面发射可见光以掩蔽发射的近红外光。 照相机适于从相机视场内的物体反射的近红外光源接收近红外光,以及在照相机视野内检测到的显示图像物体。

    • An on-board gas composition sensor is disclosed for monitoring oxygen content levels in the exhaust gas of an internal combustion engine. The gas composition sensor includes a light source for generating excitation light, e.g. in the 350-525 nm wavelength range. A sensor body of porous high-temperature fluorescent inorganic oxide ceramic exposed to the exhaust gas emits an optical fluorescence signal responsive to oxygen content in the exhaust gas upon exposure to the excitation light at 400.degree.-650.degree. C. A florescence detector receives the optical fluorescence signal from the sensor means and generates an exhaust gas oxygen content output signal in response. Fiber-optic cable can be employed for transmitting excitation light to the sensor body from a remotely located light emitter. The same or a separate fiber-optic cable can transmit the optical fluorescent signal from the sensor body to the fluorescence detector also at a remote location.
    • 公开了一种用于监测内燃机的废气中的氧含量水平的车载气体组成传感器。 气体成分传感器包括用于产生激发光的光源,例如 在350-525 nm波长范围内。 暴露于废气的多孔高温荧光无机氧化物陶瓷的传感器体在暴露于400-650℃的激发光时,响应于废气中的氧含量发射光学荧光信号。荧光检测器接收光学 来自传感器装置的荧光信号,并且响应地产生排气氧含量输出信号。 可以使用光纤电缆将激发光从远程位置的发光器传输到传感器主体。 相同或单独的光纤电缆也可以在远程位置将光学荧光信号从传感器主体传输到荧光检测器。
