Special Issue Information
Dear Colleagues,
Ultrasonic testing plays a crucial role in ensuring structural integrity and performance evaluation across the aerospace industry. However, conventional contact ultrasound methods have limitations for in situ inspection of complex aircraft components. Recently, laser-based non-contact ultrasound techniques have shown great potential to address these challenges.
By using laser sources to generate and detect ultrasound waves, laser ultrasonic methods allow for remote and versatile inspection capabilities without requiring direct probe contact. This enables the evaluation of safety-critical or hard-to-reach areas on aircraft or spacecraft. Nonetheless, applications of laser ultrasound in real aerospace systems are still limited due to technical issues such as coupling efficiency, multi-modal wave detection, and interpretation of results under service conditions. Technological advancements are much needed to address these limitations. These include, among others, the development of efficient laser ultrasound generation and detection methodologies, the optimization of signal processing algorithms for aerospace materials, and the enhancement of inspection techniques for critical aerospace components
This Special Issue aims to advance the field by bringing together the latest research. Original contributions are invited to address topics including, but not limited to, innovative laser ultrasound generation and detection techniques; multi-modal wave analysis and imaging algorithms; coupling characterization for advanced materials and surfaces; laser-based simulation of pyroshock, mechanical shock waves, or acoustic emissions; and case studies demonstrating field trials. Both theoretical and experimental studies that propel the methodology toward routine industrial deployment are welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Aerospace is an international peer-reviewed open access monthly journal published by MDPI.
