摘要： Systems for analyzing fluids (e.g., gases) include a chamber structure with a reflective inner surface, emitters, a primary detector positioned to principally detect electromagnetic energy reflected numerous times through the gas(es) and a calibration detector positioned to detect electromagnetic energy not reflected numerous times through the gas(es). Calibration may be automatically performed. The primary detector relies principally on Raleigh scattering. An optional primary detector may be positioned to principally detect Raman scattered electromagnetic energy.

摘要： A method and apparatus for irradiating a scattering medium with increased resolution. The method includes transmitting EM radiation from an Electromagnetic (EM) radiation source to a target inside a scattering medium, wherein the target encodes the EM radiation with a variance structure to form encoded EM radiation; measuring, in a detector, transmitted EM radiation comprising at least a portion of the encoded EM radiation transmitted through and exiting the scattering medium; decoding the transmitted EM radiation, comprising EM fields, in a computer, comprising selecting one or more of the EM fields having the variance structure; and irradiating the scattering medium with time reversed EM radiation from a spatial light modulator (SLM), the time reversed EM radiation generated from time reversing the EM fields having the variance structure, thereby forming a focus of the time reversed EM radiation in the scattering medium with the increased resolution.

摘要： A particle detector includes a laser, a beam shaping lens, and a pair of mirrors which reflect the shaped laser beam back and forth between the mirrors a selected number of times in order to create a sheet of light or light net between the mirrors. The path of the beam is terminated by a beam stop which contains a photodiode to monitor beam intensity and thereby system alignment. Light scattered by a particle falling through the sheet of light is gathered and transmitted to a photodiode. A peak detector provides a measure of the peak intensity of light scattered by such a particle to a microprocessor, which counts the number of particles falling through the light net in a selected time interval. The microprocessor also uses the peak intensity to estimate the size of the particle.

摘要： An arrangement for in situ determination of the quantity of turbid matter, aerosol and/or dust in flue gas which flows through a flue by measurement of intensity of light irradiated by means of an optical transmitter in the flue, and dispersed on solid or fluid dispersion particles. The dispersion light is detected by a detector which is arranged outside of the bundle of rays of the transmitter and provided with a wide angle focusing optic. A woodsche horn absorbs the not dispersed part of the bundle of rays of the transmitter. The light source of the transmitter is formed as a xenon spark discharger with intensity maximum in the region of 350-600 nm, the detector signal is evaluated by an evaluating electronic circuit. The arrangement determines extremely low quantities of harmful matter.

摘要： An apparatus, a system and a method use a light-emitting diode (LED) to identify the presence of a material in a gas and/or a fluid and/or to determine properties of the material. The LED and a light detector may be used to determine a chemical compound in the material. The gas and/or the fluid may be located in a chamber. A first light detector may be positioned on the opposite side of the chamber relative to the LED, a second light detector may be positioned on the same side of the chamber as the LED, and/or a third light detector may be positioned inside the chamber. Additional light detectors with coatings may enable measurements to be corrected for the effects of temperature. The light detectors may determine light reflection, light refraction, light transmission, light diffraction, light interference, light diffusion, light collimation, light absorption and/or light focusing of the material.

摘要： A measuring instrument for simultaneous in situ determination of the spectral scatting and absorption coefficient, which can also be called an extinction meter, has a modulated light source and an optical system encompassing the hemisphere; the optical system has a multiply folded ray path with a focal point in the volume to be measured, and through this system the measurement signal is projected to detectors. The scattering measurement signals, which are maximally enlarged in this way, are then separated from those for the absorption. The extinction meter also has not only an integrating nephelometer for monitoring purposes but also a transmission meter for low transmission factors. Because of the small three-dimensional size and the streamlined shape of the measuring portion of the extinction meter, the extinction meter can be carried in aircraft and surface vehicles. Because of the disposition of the optical system, the error in the measurement values is negligible, in comparison with other instruments with which only the scattering coefficient can be determined. Moreover, the calibration value during a measurement phase can be determined both automatically and manually. Contamination of the instrument with gas to be measured is reduced, by the stabilization of a turbulence ring by means of baffles. Moreover, interference with the flowing aerosol on the part of the instrument is largely eliminated via a hoop-like hood functioning like a wing-tip slot.
摘要翻译：用于同时原位测定光谱散射和吸收系数的测量仪器（也称为消光计）具有调制光源和包围半球的光学系统; 该光学系统具有在要测量的体积中具有焦点的多重折叠的光线路径，并且通过该系统将测量信号投影到检测器。然后以这种方式最大化地扩散的散射测量信号与用于吸收的散射测量信号分开。灭火表不仅具有用于监测目的的积分浊度计，而且还具有低传输系数的传输仪表。由于消光表的测量部分具有小的三维尺寸和流线型的形状，所以消光计可以被携带在飞机和地面车辆中。由于光学系统的配置，与其中只能确定散射系数的其他仪器相比，测量值的误差可以忽略不计。此外，可以自动和手动地确定测量阶段期间的校准值。通过挡板稳定湍流环，仪器与待测气体的污染减少。此外，通过像翼尖槽一样的环形罩大大消除了对仪器部分流动的气溶胶的干扰。
