Advances and Applications of Laser Measurements

Dear Colleagues,

Laser measurement technology is a high-precision and high-resolution method based on lasers’ well-known characteristics: monochromaticity, coherence, and directionality. Its applications span industrial manufacturing, medical imaging, and environmental monitoring. Beyond these, they include optical coherence tomography (OCT) technology, which can assist in medical diagnosis and the formulation of treatments. While its potential for use is constantly growing, LiDAR currently finds its application in intelligent driving, among a number of other contexts.

Based on these prospects, the pursuit of increasingly accurate and stabile laser measurement has become significant, and these aims should be considered in the design of laser measurement systems, as they are particularly beneficial in precision measurements and the observation of fine structures. The potential of laser measurement extends beyond mere performance improvement. It involves developing multimodal systems to capture broader information, expanding measurement boundaries to address complex environments, and integrating real-time monitoring and automation for enhanced efficiency and productivity across various applications.

This Special Issue focuses on principles, methods, and latest developments in laser measurement technology, alongside specific application cases across diverse fields. Specifically, we aim to offer a platform for the introduction of techniques and applications of laser measurements, including laser coherent detection, laser damage monitoring technology, etc. Researchers are invited to submit their contributions to this Special Issue. Topics include, but are not limited to, the following:

• Laser interferometry;
• Laser measurement applications;
• LiDAR;
• Optical fiber sensing;
• 3D laser scanner;
• Structured-light 3D surface imaging;
• Laser frequency combs;
• Optical coherence tomography (OCT);
• Optical frequency domain reflectometry (OFDR);
• Spectrometer and spectral analysis.

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 250 words) can be sent to the Editorial Office for assessment.

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. Photonics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
