Image denoising in acoustic field microscopy
Shubham Kumar Gupta, Azeem Ahmad, Prakhar Kumar +2
Scanning acoustic microscopy (SAM) has been employed since microscopic images are widely used for biomedical or materials research. Acoustic imaging is an important and well-establ…
Wave propagation in anisotropic crystal using point contact excitation and detection method
Varun Bhardwaj, Kaushik Shukla, Frank Melandsø +1
Lithium Niobate (LiNbO) is a piezoelectric crystal with a high electromechanical coupling coefficient. The development and miniaturization of acousto-electronics, and acousto-o…
Multiple damage detection in piezoelectric ceramic sensor using point contact excitation and detection method
Sayantani Bhattacharya, Nitin Yadav, Azeem Ahmad +2
Lead Zirconate Titanate [(ZrxTi1-x)O3 ]is used to make ultrasound transducers, sensors, and actuators due to its large piezoelectric coefficient. Several surfaces and subsurface mi…
Surface acoustic waves inside polystyrene microparticles through photoacoustic microscopy
Abhishek Ranjan, Anowarul Habib, Azeem Ahmad +2
We demonstrate surface acoustic waves inside polystyrene microspheres of different sizes experimentally through photoacoustic microscopy and validate the experimental result with s…
