Sensing with Structured Beams Structured beams are optical fields that are generated to have very specific spatially patterned phase and intensity profiles. There are a wide variety of these beams that interact with media and the environments in unique ways depending on their spatial profile. In this talk we will discuss the use of these beams for the amplification of very small non-linear acoustic behaviour in air, the determination of particulate size based on optical aberrations, and, when coupled with machine learning, for revealing usually unobservable physical parameters in the environment. |
