Special Issue Information

Dear Colleagues,

Optical metrology has emerged as a powerful tool for addressing critical challenges in environmental monitoring, offering high sensitivity, non-invasiveness, and spatially-resolved measurements. As global concerns over climate change, pollution, and food security intensify, the need for accurate, real-time, and scalable monitoring techniques is becoming paramount. This Special Issue focuses on cutting-edge optical techniques applied to environmental monitoring tasks such as temperature field mapping in natural and industrial settings, the of microplastics in air and water, and the evaluation of agricultural products for quality and safety.

We invite contributions exploring the application and advancement of optical methods including speckle metrology, digital holography, interferometry, polarimetry, and hybrid optical systems. These approaches offer promising capabilities for remote sensing, multi-scale analysis, and in-field deployment under harsh environmental conditions. The integration of model-based analysis, machine learning, and adaptive optics further enhances their utility for complex and dynamic environments.

Potential topics include, but are not limited to, the following:

  • Optical temperature and flow diagnostics in natural ecosystems;
  • Microplastic detection and characterization;
  • Non-destructive optical techniques for crop and soil monitoring;
  • Advances in speckle-based and interferometric techniques;
  • Holographic and 3D imaging for environmental assessment;
  • Portable and real-time optical sensing systems.
  • Advanced polarimetric techniques for non-invasive assessment;
  • Novel computational algorithms; deep learning methods for image reconstruction and optimization.

Original research, case studies, tutorials, and comprehensive reviews are all 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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
