摘要： Crime scene lighting devices are used in forensic criminology for illumination and investigation at crime scenes using fluorescence excitation. High radiation powers are required both for white light in the so-called general search and for the criminologically relevant UVA-blue-green range. Moreover, it should be possible for the crime scene investigator to use the forensic lighting device portably and independent from the public power supply. The present disclosure relates to a suitable crime scene light device with a mercury ultra high pressure lamp as the light source, a light guide and terminals for operating the lamp selectively with an accumulator or the public power supply system. A suitable carrier bag, a so-called lorgnette with various longpass filters and a cross-section converter for visualizing shoeprints form useful accessories of the forensic lighting device.

摘要： An instrument for determining the concentration of a particular gas that might be present in a sample has no moving parts and is extremely compact and inexpensive. A novel waveguiding structure serves both as an optical element and as the sample chamber. As an optical element, the waveguiding structure collects radiation from a blackbody source located at the entrance end of the waveguiding structure and conducts the radiation through the waveguiding structure, concentrating it on two infrared detectors mounted at the opposite end of the waveguiding structure. As a sample chamber, the waveguiding structure causes the radiation to undergo multiple reflections that result in the average path length being substantially greater than the physical length of the waveguiding structure. Each of the detectors has its own optical filter, and baffling assures that each detector responds only to radiation which has passed through its filter. One filter defines a spectral passband that coincides with the infrared absorption band of the gas to be measured. The other filter defines a non-absorbing or neutral passband. The electrical signals produced by the detectors are processed to provide a ratio, the value of which is related to the concentration of the particular gas to be detected.

摘要翻译： 用于确定样品中可能存在的特定气体的浓度的仪器没有移动部件，并且非常紧凑和便宜。 新颖的波导结构既用作光学元件又用作样品室。 作为光学元件，波导结构收集来自位于波导结构的入口端的黑体源的辐射，并将辐射传导通过波导结构，将其集中在安装在波导结构的相对端的两个红外检测器上。 作为样品室，波导结构导致辐射经历多次反射，导致平均路径长度远大于波导结构的物理长度。 每个检测器都有自己的光学滤波器，并且挡板确保每个检测器仅响应已经通过其过滤器的辐射。 一个滤光器定义与待测气体的红外吸收带一致的光谱通带。 另一个滤波器定义了非吸收或中性通带。 由检测器产生的电信号被处理以提供一个比率，其值与待检测的特定气体的浓度有关。

摘要： Thermally tunable optical sensors are used in sampling tools for analysis of samples from a wellbore. The thermally tunable optical sensors generate a series passbands of wavelength emissions and detect attenuation in a signal thereof. The attenuation detected is processed and used to determine aspects of the samples. Analysis may be completed remotely (outside of the wellbore), within the wellbore (during drilling or otherwise), or as a part of another process such as fluid management, transport and refinement.
