    • An aircraft landing and/or taxiing system has a plurality of landing zone, runway, and/or taxiway lights capable of receiving information signals and transmitting optically signals representative of the information signals. A processing system for providing the information signals to the plurality of lights is also used. The system also comprises a sensor tuned to receive light of a specific range of wavelengths, the light being emitted from the lights. Also, a processing system coupled to the sensor and configured with software to interpret signals received by the sensor is used. Program code runs on the processing system. The program code is configured to determine the location of an aircraft on the taxiway based on the light signal received from one or more of the taxiway lights. Also, the aircraft landing and/or taxiing system utilizes modulated lights to provide information pertinent to aircraft landing and/or taxiing operations.

    • The laser range finding system includes a light detection and ranging (LIDAR) sensor unit (SU) and a LIDAR processor unit (PU). The LIDAR SU is for transmitting light pulses and receiving resulting input light signals reflected from objects within the field of view of the SU. The LIDAR SU includes a flash LIDAR illuminating laser source for transmitting light pulses. The LIDAR illuminating laser source includes an illuminating laser and zoom optics operatively associated with the laser. A LIDAR receiver receives resulting input light signals reflected from the objects. The LIDAR receiver includes a sensor; and, a flash readout integrated circuit (IC). The flash readout IC measures the transit time of the light pulses. The LIDAR processor unit (PU) is operatively associated with the LIDAR SU and it utilizes flash LIDAR ranging. A power source is operatively coupled to the LIDAR PU. Zooming of the transmitted light pulses results in the received resulting input light signals illuminating a relatively reduced area of the frame. Thus, a flash LIDAR image of relatively reduced resolution but enhanced range is provided by utilization of the transit time measurements.
    • 激光测距系统包括光检测和测距(LIDAR)传感器单元(SU)和激光雷达处理器单元(PU)。 LIDAR SU用于发送光脉冲并接收从SU视野内的对象反射的结果输入光信号。 激光雷达SU包括用于发射光脉冲的闪光LIDAR照明激光源。 LIDAR照明激光源包括与激光器可操作地相关联的照明激光器和变焦光学元件。 LIDAR接收器接收从对象反射的结果输入光信号。 激光雷达接收机包括传感器; 和闪存读出集成电路(IC)。 闪光读数IC测量光脉冲的通过时间。 LIDAR处理器单元(PU)与LIDAR SU可操作地相关联,并且其使用闪光LIDAR测距。 电源可操作地耦合到激光雷达PU。 透射光脉冲的变焦导致接收的所得到的输入光信号照亮帧的相对缩小的区域。 因此,利用通过时间测量提供了相对降低的分辨率但是增强的范围的闪光LIDAR图像。
