In this work we will review some of the novel applications, recently proposed, where the use of structured light has played a crucial role. First, in the field of laser remote sensing, we discuss about a technique that allows to measure, in a direct way, the component of velocity perpendicular to the line of sight. This technique has found applications in the field of fluid dynamics, where an effective and simple optical technique capable to provide accurate measurements of ow vorticity, the tendency of a ow to rotate, was recently demonstrated. We then move to the field of profilometry to revise the key ideas behind a highly sensitive interferometric technique for thickness measurement, which is based on mode projection. We finally enter the field of optical activity to explore a novel proposal where an enhanced interaction between the handedness of structured light and chiral molecules was predicted. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
