The purpose of this Special Issue is to contribute to the state-of-the-art by introducing the latest developments in optical pressure (oxygen) and temperature imaging sensors based on the photochemical reaction and their applications. This Special Issue welcomes submissions of original research, novel developments, and experimental studies on optical sensors and their application in optical sensing of thermofluid dynamics.
In recent years, the development of optical pressure (oxygen) and temperature sensors has been remarkable. A pressure sensor based on oxygen quenching has significantly improved the time response. With the improvement of high-speed cameras and the development of measurement methods and post-measurement image processing, the time and pressure resolutions of the pressure imaging measurements are greatly extended. Optical pressure sensors are also applied to measurement on deformed and free-flight objects. Temperature sensors are used not only to measure temperature distribution, but also for a wide range of applications such as to measure heat flux and shear stress, and visualize boundary layer transitions. With the development of sensors, hardware, metrology, and post-image processing, we will be able to apply them to a wider range of measurements. We contribute to the development of new sensing technologies by featuring the latest research cases.

Optical pressure and temperature sensors, known as pressure- and temperature-sensitive paints, are photochemical sensors based on oxygen quenching and temperature quenching, respectively. These sensors are receiving more and more attention in recent years and are being used by a wider range of researchers and engineers. Therefore, it is of great significance to feature these sensors in Sensors.

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 papers will be 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. Sensors 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 2200 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.
