摘要： An optical system for measuring in real-time the spatial distribution of aerosol particles, such as pesticides or the like, sprayed from a vehicle over an agricultural field. An optical sensor is mounted directly on the vehicle and sends an excitation light beam through the aerosol as it is being sprayed. The resulting scattered light is received and analyzed to deduce therefrom information on the spatial distribution of the particles. This information is relayed to a processing unit, which in turn provides spraying instructions, for example a warning signal, to the operator of the system. The spraying of the aerosol can therefore be controlled in real-time to avoid contamination of sensitive areas.

摘要： A rangefinding device and a method for determining the range of an object from a rangefinding device are provided. A train of light pulses each having an emission time and a pulse duration is generated. The pulse duration is set to twice the round-trip time to a maximum range of the device. The light pulses are reflected back toward the device by the object and detected according to three time intervals, respectively determined by a background gate, a ranging gate and a pulse energy gate. The light energy received during each interval is integrated and the integrated light value corresponding to the ranging gate is normalized using the values from the other two intervals. The range of the object is determined from the normalized ranging measurement and calibration data.

摘要： A flat spatial response LIDAR apparatus for detecting particles within a short range is provided. The apparatus includes a light source projecting a light beam which is back-scattered by the particles to be detected. The back-scattered light is received, detected and analyzed. A spatial filter spatially filters the received back-scattered light in order to flatten the spatial response of the apparatus, so that a same concentration of particles at any distance within the short range will generate a signal of substantially the same intensity. This is for example accomplished by a properly profiled mask disposed in front of the detector, or a plurality of spatially distributed waveguides. As a result, the LIDAR apparatus can compensate for the 1/r 2 dependence, or other dependences of the back-scattered light on the distance r .
