Image inpainting in acoustic microscopy
Habib, Anowarul; Banerjee, Pragyan; Mishra, Sibasish; Yadav, Nitin; Agarwal, Krishna; Melandsø, Frank; Prasad, Dilip K (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-27)Scanning acoustic microscopy (SAM) is a non-ionizing and label-free imaging modality used to visualize the surface and internal structures of industrial objects and biological specimens. The image of the sample under investigation is created using high-frequency acoustic waves. The frequency of the excitation signals, the signal-to-noise ratio, and the pixel size all play a role in acoustic image ... -
Multiple Damage Detection in PZT Sensor Using Dual Point Contact Method
Bhattacharya, Sayantani; Yadav, Nitin; Ahmad, Azeem; Melandsø, Frank; Habib, Anowarul (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-25)Lead Zirconate Titanate (PZT) is used to make ultrasound transducers, sensors, and actuators due to its large piezoelectric coefficient. Several micro-defects develop in the PZT sensor due to delamination, corrosion, huge temperature fluctuation, etc., causing a decline in its performance. It is thus necessary to identify, locate, and quantify the defects. Non-Destructive Structural Health Monitoring ...
