摘要： A method and an apparatus for laser marking indicia in the volume of gemstones such as diamonds, the indicia being made up of a plurality of microscopic dot-shaped marks whose build-up can be initiated by exposing naturally-occurring internal defects or impurities in the volume of a gemstone to a tightly focused train of laser pulses. Authentication data is encoded in the gemstone from the relative spatial arrangement of the dot-shaped marks that form the indicium. Taking advantage of the presence of otherwise invisible defects in the gemstone allows for inscribing indicia with laser pulses carrying energies substantially lower than the threshold energy required for inscribing in the volume of a perfect gemstone material. The marking process is then much less susceptible to inflict damages to the surface of the gemstone, and the marking can be performed using a broad variety of femtosecond laser systems. The dot-shaped marks engraved at a depth below the surface of a gemstone can be made undetectable with the unaided eye or with a loupe by limiting their individual size to a few micrometres, while devising indicia made up of only a few marks. As a result, the marking does not detract from the appearance and value of the gemstone. The procedure for laser marking accounts for the random spatial distribution of the defects present in natural gemstones as well as for their strongly localized character. The presence of an indicium can be detected by using a dedicated optical reader that can be afforded by every jewellery store.
摘要翻译：一种用于在诸如金刚石的宝石体积中的激光标记的方法和装置，所述标记由多个微小的点状标记组成，所述微小点状标记的积聚可通过暴露天然存在的内部缺陷或杂质而引发宝石的体积到紧密聚焦的激光脉冲序列。从形成标记的点状标记的相对空间排列，认证数据被编码在宝石中。利用宝石中其他不可见缺陷的存在，允许用激光脉冲刻印标记，该激光脉冲承载能量大大低于在完美宝石材料的体积上所需的阈值能量。然后，标记过程不太可能对宝石表面造成损害，并且可以使用各种飞秒激光系统进行标记。雕刻在宝石表面下方的深度上的点状标记可以通过将其个体尺寸限制在几微米之内，而不用肉眼检测，或者通过将其个体尺寸限制在几微米之外，同时设计仅由几个标记构成的标记。因此，标记不会降低宝石的外观和价值。激光标记的程序解释了天然宝石中存在的缺陷的随机空间分布以及它们的强烈局部化特征。可以通过使用可由每个珠宝店提供的专用光学读取器来检测标记的存在。

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： An object-detecting lighting system (10) comprises a light source (12) emitting visible light. A source controller (14) is connected to the light source (12) to drive the light source (12) into emitting the visible light in a predetermined mode. An optical detector (16) is positioned with respect to the light source (12) and is adapted to detect the visible light as reflected/backscattered by an object (A). A data/signal processor (18) is connected to the source controller (14) and the optical detector (16) to receive detection data from the optical detector (16). The data/signal processor (18) produces a data output associated to the object (A) as a function of the predetermined mode and the detection data.

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.
摘要翻译：一种用于实时测量在农田上从车辆喷射的气溶胶颗粒（例如农药等）的空间分布的光学系统。光学传感器直接安装在车辆上，并且在喷雾时将激发光束通过气溶胶。所得到的散射光被接收和分析，从而推导出关于颗粒的空间分布的信息。该信息被中继到处理单元，处理单元又向系统的操作者提供喷射指令，例如警告信号。因此可以实时控制气雾剂的喷雾，以避免敏感区域的污染。
