The photoacoustic signal in a closed T-cell resonator is generated and measured using laser based photoacoustic spectroscopy. The signal is modelled using the amplitude mode expansion method, which is based on eigenmode expansion and introduction of losses in form of loss factors. The measurement reproduced almost all the calculated resonances from the numerical models with fairly good agreement. The cause of the differences between the measured and the simulated resonances are explained. In…

Finite Element Simulation of Photoacoustic Pressure in a Resonant Photoacoustic Cell Using Lossy Boundary Conditions

The finite-element method (FEM) is used to simulate the photoacoustic signal in a cylindrical resonant photoacoustic cell. Simulations include loss effects near the cell walls that appear in the

Finite element calculation of photoacoustic signals.

The method is verified for cylindrical cells with excellent accordance and the application to photoacoustic cells of unconventional shape yields good agreement with experimental data.

Open Photoacoustic Cell for Blood Sugar Measurement: Numerical Calculation of Frequency Response

A numerical approach based on the Finite Element (FE) Method has been adapted to obtain the frequency response of the open cell and, despite the fact that loss due to sound radiation at the opening is not included, fairly good accordance with measurement is achieved.

Off-beam quartz-enhanced photoacoustic spectroscopy.

This OB-QEPAS configuration not only allows for use of larger excitation optical beams and facilitating optical alignment but also provides higher enhancement of photoacoustic signals than previously published results based on the common on-beam QEPAS under the same experimental conditions.

Double acoustic microresonator quartz-enhanced photoacoustic spectroscopy.

Quartz-enhanced photoacoustic spectroscopy (QEPAS) based on double acoustic microresonators (AmRs) provides two independent detection channels that allow optical signal addition or cancellation from different optical wavelengths and facilitate rapid multigas sensing measurements, thereby avoiding laser beam combination.

Quartz-enhanced photoacoustic spectroscopy.

A new approach to detecting a weak photoacoustic signal in a gas medium is described. Instead of a gas-filled resonant acoustic cavity, the sound energy is accumulated in a high- Q crystal element.

Challenges in the Design and Fabrication of a Lab-on-a-Chip Photoacoustic Gas Sensor

The new, or more intense, challenges faced if downscaling is continued are discussed, including the limit of validity of the continuum hypothesis and solutions exist to realize a complete lab-on-a-chip, even if it remains a demanding integration problem.

Windowless ultrasound photoacoustic cell for in vivo mid-IR spectroscopy of human epidermis: low interference by changes of air pressure, temperature, and humidity caused by skin contact opens the possibility for a non-invasive monitoring of glucose in the interstitial fluid.

It is demonstrated here that this approach can be used for continuous and non- invasive monitoring of the glucose level in human epidermis, and thus may form the basis for a non-invasive monitoring for diabetes patients.
