A Comparison of Acoustic Field Measurement by a Microphone and by an Optical Interferometric Probe

open access: yesActa Polytechnica, 2002
The objective of this work is to show that our optical method for measuring acoustic pressure is in some way superior to measurement using a microphone. Measurement of the integral acoustic pressure in the air by a laser interferometric probe is compared

Non-conventional ultrasound transducer geometry facilitates remote light control within samples

open access: yesJPhys Photonics
Light control inside a sample is central in areas as relevant as life sciences and material sciences. Traditionally, this is achieved by using external devices, which can be limited by a short working distance, scattering-limited focusing depth, and ...
