Laser Doppler vibrometers, laser Doppler anemometers, laser surface velocimeters, and laser Doppler extensometers are sensors based on laser Doppler technology. Such sensors utilize an interferometric detection scheme and broadband demodulation of the derivative of the interference phase. Since the derivative of the interference phase corresponds to the laser Doppler frequency shift generated by a moving target reflecting or scattering the measuring laser beam, such sensors are called laser Doppler sensors.
Special techniques such as heterodyning, signal diversity, and multiwavelength length detection make laser Doppler sensors reliable, accurate, and highly sensitive. For example, the detection of backscattered measuring light power in the femtowatt range is just as possible as the detection of picometer deflections. Laser Doppler sensors therefore influence many research areas and industrial applications. Such sensors are commercially available and widely used. However, laser speckles for measurement on rough surfaces have a negative influence on laser Doppler sensors. The high intensity dynamics of laser Doppler sensors were the only lever to deal with the influence of laser speckles. Recent developments have even enabled speckle-insensitive laser Doppler sensors. The treatment of laser speckles is only one example of the many research topics in the field of laser-Doppler sensors that are currently being addressed by various research groups worldwide. Other topics include, for example, suppression of the sensor’s self-movement, tracking of moving objects, multichannel detection, fusion of data with that from other sensors and measurements of microscopic objects.
This Special Issue on laser Doppler sensors deals with the latest findings and developments, and contemporary applications in sensors based on laser Doppler techniques.Dr. Christian Rembe

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 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.
