Ultrasonic testing (UT) is widely used for the nondestructive testing (NDT) of composite materials in the aerospace industry. Liquid-coupled piezoelectric ultrasonic transducers are the most common technology used in this field; however, liquid coupl

A novel fast proximal scanning method, to the best of our knowledge, termed fiber-core-targeted scanning (FCTS), is proposed for illuminating individual fiber cores sequentially to remove the pixelation effect in fiber bundle (FB) imaging. FCTS is ba

In this paper three case studies of the application of a compact non-contact, non-destructive setup are presented. The herein employed method is based on the air-coupled detection of acoustic waves in the frequency range up to 2 MHz.

We present a dual modality functional optical coherence tomography and photoacoustic microscopy (OCT-PAM) system. The photoacoustic modality employs an akinetic optical sensor with a large imaging window. This imaging window enables direct reflection

Air-coupled ultrasound (ACU) is already an established method for the non-destructive failure inspection of carbon fiber reinforced polymers (CFRP). In the through-transmission setup, plate-like structures are placed between the ultrasound (US) sourc
