Abstract:

Infrared laser photo-acoustic spectroscopy provides very high sensitivity of a gas sample analysis when high-power tunable laser radiation sources and resonant photo-acoustic detectors (PADs) are used. In the resonant PAD, the acoustic signal generated by absorbed laser radiation in a measurement chamber is amplified proportionally to a Q-factor of the acoustic resonator. But, compact tunable high-power lasers (with power above 100 mW) still are not widely spread in the terahertz spectral range. One of the ways to achieve an acceptable sensitivity of terahertz photo-acoustic spectroscopy is us

Abstract:

Sintering kinetics of NiO was investigated using photo acoustic spectroscopy This method was used to follow the change of phase and amplitude of the photo acoustic signal of nickel-oxide samples sintered at 1373 K for 15-240 min. as a function of modulation frequency of the laser beam. Fitting of experimental data enabled determination of photo acoustic properties including thermal diffusivity of sintered nickel-oxide. Analysis of the change of sample density during sintering showed that the sintering process of this material can be observed from the viewpoint of activated volume and the chang

Abstract:

An ultra-high sensitivity multi-molecule sensor based on a photo-acoustic cell with two perpendicular acoustic resonators and a common microphone has been reported. In this work, a 4.5 µm distributed-feedback quantum cascade laser and a 1.5 µm external cavity diode laser (EC-DL) were used as optical excitation sources. Considering the spectral ranges of the lasers used, it is possible to analyze eight molecules (QCL:N2O and CO2, EC-DL: H2O, H2S, NH3, CO, CH4, and C2H2). The N2O molecule was used to evaluate the performance of the photo-acoustic spectroscopy (PAS)-based sensor. A sensitivity of

Abstract:

Multiple breath washout (MBW) of inert gas for assessment of airway disease in children is an emerging technique. In many studies Lung Clearance Index (LCI), derived from multiple breath washout of SF6, is more able to detect early or mild lung disease than standard lung function measurements. It is also able to detect very early lung disease in progressive conditions such as Cystic Fibrosis (CF). Where infants born with this condition were thought to have minimal lung disease activity, LCI is higher in these children than healthy controls.

Abstract:

The acousto-optic couplings mechanisms are investigated theoretically in photonic and phononic crystals with simultaneous band gaps. The authors have focused on the acousto-optic couplings inside a phoXonic cavity by taking into account two coupling mechanisms, the photo elastic effect and effect of movement of the interfaces. They discuss the symmetry of modes to distinguish those that don't interfere in an efficient way. They calculate the modulation of the frequency of the photonic mode during a period of acoustic oscillations with a finite element method (FE) (COMSOL®Multiphysics). The two

Abstract:

Experimental tests in model-scale are the currently established (and more reliable) methods for the propeller acoustic characterization. However, they are affected by uncertainties mostly due to scale effects, which make it difficult to consistently reproduce in model-scale some of full-scale functioning conditions. In order to cope with this issue, it is interesting to define empirical formulations to shape the most significant cavitating phenomena in terms of underwater radiated noise spectrum. A suitable approach for the determination of such formulations may consist in the experimental cha

A combined theoretical and experimental analysis of thermoacoustic interaction mechanisms of a lean pre-mixed swirl-stabilized gas turbine burner is presented. A full-scale gas turbine burner has been tested in an atmospheric test rig. The test facility was equipped with loudspeakers to excite the acoustic field and with arrays of microphones to measure the response of the acoustic field to the forcing signal. With this set-up transfer matrices relating the acoustic pressure and velocity on both sides of the flame front have been measured. A laser absorption measurement technique allowed for m

In addition, multiple types of damage precursors including micro-scale matrix cracks, fiber pull-out from matrix, and fiber breakages, are extremely difficult to detect due to the limitation of resolution of current non-destructive evaluation (NDE) technologies.

Abstract:

Semiconductor alloys of InGaAsP are of great importance for the technology of optical communication. Relatively few experiments which measure the ultrafast response of photoexcited carriers in these materials have been reported. In this contribution, the dynamics of dense electron-hole plasmas in InGaAsP films subsequent to ultrashort optical pulse excitation are examined by probing transient transmission and reflection. Typical results are shown in Fig. 1. From the transmission data one sees short-time bleaching or gain, long-time induced absorption, and regular oscillations of the induced ab
