In this paper, we presented the optical technical to extract size and refractive index of the non-absorbing particles. It is based on the inverse Mie for calculating the Mie scattering amplitudes S1 (θ) and S2 (θ) from their measurement of the elec

This paper proposes an approach for acoustic field imaging using simultaneous multi-view digital holography based on three-color digital off-axis holography. Considering spatio-chromatic multiplexing and the recording with a monochrome sensor, the nu

Digital Holography and 3-D Imaging 2022.
This paper discusses on distortion and bias in digital holographic imaging applied to the visualisation of acoustic fields. Distortion due to exposure time and bias due to the propagation of the laser beam in the acoustic field are investigated.

This paper proposes a digital color holographic approach for multi-view imaging of the amplitude and phase of acoustic fields. Experimental results with a 40 kHz acoustic emitter demonstrate the proof-of-concept of multi-view imaging.

In this paper, we demonstrate the shaping of an incident Gaussian beam into a tunable hyperbolic Airy-like beam, using an acoustooptics cell. The latter contains a transparent liquid (water), where an ultrasound wave propagating and creating a sinuso
