In this study, we propose a robust photoacoustic (PA) signal processing framework for a
material independent defect detection using empirical mode decomposition (EMD) and …

Subsurface imaging is challenging; it is difficult to detect objects visually. In this research, a
novel non-contact photoacoustic (PA) imaging system was developed to detect subsurface …

A low-cost real-time photoacoustic microscopy (PAM) has been developed by replacing the
sophisticated laser and transducer with a very low-energy diode laser and a condenser …

Linear assumption on the level of stiffness in a tissue shows a significant correlation with
disease. Photoacoustic imaging techniques that are non-contact by design have been …

It is needed to avoid toxicity and corrosion in terms of improving the aesthetic magnitude of
steel components used in electrical appliances, recreational materials, and construction of …

Spun-part wall thickness is a key output parameter of spinning products. Thickness affects
the spun part strength: Low thickness leads to cracks on spinning products. Hence, it is …

This study develops a subsurface detection system based on a photoacoustic effect. The
main parts of the system are a laser diode as an exciter, a standard microphone as an …

Istilah yang umum digunakan untuk area kerusakan pada bagian permukaan adalah
surface crack detection. Beberapa alat telah dikembangkan untuk mendeteksi surface crack …

This paper reports the result of measurement and analysis of the shape of photoacoustic
signal emitted from an object which is a piece of carbon paper, excited by a diode laser …

Bu çalışmada, görgül kip ayrışımı (GKA) ve makine öğrenimi algoritması kullanılarak
malzeme kusurlarının tespiti için bir fotoakustik (FA) sinyal işleme çerçevesi önerilmiştir …
