摘要： An apparatus and method are disclosed for securing a substantially circular wafer comprising a chuck comprising a plurality of tensioning grooves each comprising at least one arcuate bend having a bend radius substantially less than an outer region radius, and a vacuum source interconnected with each of the grooves. When the wafer is placed upon the surface concentric with the chuck centre and the vacuum source applied to the grooves, the wafer is held securely to the surface. Additionally, there is disclosed an apparatus for securing a wafer comprising a chuck and a collar comprising a rigid support and an o-ring, the o-ring having a diameter slightly smaller than the outer perimeter. When the wafer is lowered onto the surface in a position concentric with the check centre, the collar is placed against the upper surface concentric with the perimeter and the vacuum source is applied securing the wafer to the surface.

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：一种用于在诸如钻石的宝石体积中的激光标记的方法和装置，该标记由多个微小的点状标记组成，其积聚可以通过暴露天然存在的内部缺陷或杂质而引发一个宝石的体积到一个紧密集中的激光脉冲序列。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，该激光脉冲承载的能量大大低于在完美宝石材料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，并且标记可以使用各种各样的飞秒激光系统进行。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与肉眼无关，或者通过将其个体尺寸限制在几微米之内，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 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 .

摘要： The invention is specially directed towards intermittent motion packaging machines where the packages are momentarily immobilized at a forming station for the time duration of the package sealing and cutting. The polymeric sheets or films (24) are sealed and cut after being exposed to a laser beam (20) in a controlled and optimized manner. The laser beam (20) is shaped with appropriate optical elements (56) to provide a desired intensity profile in the section of the films to be sealed or sealed and cut. With this method, a package (15) can be sealed and cut simultaneously in one exposure step. An optical clamp (30, 31) holds the films (40, 41) together while they are being sealed by the laser (20). The optical clamp (30, 31) can reflect back to the films, partially or totally, the laser beam intensity that has not been previously absorbed. The optical clamp (30, 31) further allows to monitor the sealing and cutting process while the process is being performed.

摘要： A system and method to improve the accuracy of the measure of constituent element(s) in a sample containing domains potentially including the constituent element(s) are described herein. For each domain, the volume of the domain is estimated and the concentration of the constituent element(s) in the domain is determined using LIBS. When all the domains have been analyzed, the volumetric concentration of the domains is summed and divided by the total volume of the sample. Accordingly, by limiting the concentration analysis to separate domains, it is possible to improve the accuracy of the concentration analysis.
摘要翻译：本文描述了提高包含可能包括构成元件的域的样品中组成元素的测量精度的系统和方法。对于每个域，估计域的体积，并使用LIBS确定域中的组成元素的浓度。当所有域被分析时，将域的体积浓度相加并除以样品的总体积。因此，通过将浓度分析限于分离的区域，可以提高浓度分析的准确性。
