By field Using AND/OR By author
This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Sound field reconstruction based on the acousto-optic effect

Torras Rosell, Antoni; Barrera Figueroa, Salvador; Jacobsen, Finn

Inter- Noise 2011 Proceedings — 2011

be measured with a laser Doppler vibrometer; furthermore, it can be exploited to characterize an arbitrary sound field using tomographic techniques. This paper briefly reviews the fundamental principles governing the acousto-optic effect in air, and presents an investigation of the tomographic reconstruction

Holographic reconstruction of sound fields based on the acousto-optic effect

Fernandez Grande, Efren; Torras Rosell, Antoni; Jacobsen, Finn

Proceedings of Internoise 2013 — 2013

Recent studies have shown that it is possible to measure a sound field using acousto-optic tomography. Theacousto-optic effect, i.e., the interaction between sound and light, can be used to measure an arbitrary soundfield by scanning it with a laser Doppler vibrometer (LDV) over an aperture

Three-dimensional reconstruction of sound fields based on the acousto-optic effect

Fernandez Grande, Efren; Torras Rosell, Antoni

Acoustical Society of America. Journal — 2013, Volume 134, Issue 5, pp. 3998-3998

of sound pressure fields from acousto-optic measurements in the audible frequency range, based on Fourier transforms and elementary wave expansion methods. The present study examines the complete reconstruction of the sound field from acousto-optic measurements, recovering all acoustic quantities
