In this article, we present an overview of recent progress in non-contact remote optical
detection of ultrasound in application to nondestructive testing and evaluation of materials …

Based on a synthesized laser ultrasonic array, full matrix capture can be used to acquire
data, which can then be post-processed using the total focusing method. However, this …

Microscopic defects in flip chips, originating from manufacturing, significantly affect
performance and longevity. Post-fabrication sampling methods ensure product functionality …

Based on the proposed quantitative, nondestructive, and noncontact thermoelastic laser
tap** (LT) reconstruction algorithm, this study is able to detect a single debonding wall …

Ultrasonic methods are widely used for the detection and characterisation of defects in multi-
layered bonded composites. However, quantitative reconstruction of defects, such as …
