The laser is one of the remarkable inventions of the 20th century that provided the most innovative and valuable tool for experimental fluid mechanics. Technological developments in lasers, magnetic resonance imaging, synchrotron and X-ray imaging, detectors, electronics, computers, and, recently, AI tools are the source of new techniques, improved accuracy, higher spatial or temporal resolution, and new applications.  Over the past 40 years, The International Symposia on Applications of Laser and Imaging Techniques to Fluid Mechanics, often referred to simply as the "Lisbon Symposia", have been persistently providing forums for promoting the interchange of new ideas on the development of advanced techniques for flow measurement and on the latest applications in the field.
