Aston University researchers develop new technique using light for non-invasive medical diagnostics

Researchers at Aston University have developed a new technique using Orbital Angular Momentum (OAM) light, which could enhance non-invasive medical diagnostics and optical communication. This method improves imaging and data transmission through biological tissues. The study shows that OAM light maintains its phase characteristics even in scattering media, allowing for highly sensitive detection of small changes. This capability could reduce the need for invasive procedures like surgeries and biopsies. The research, published in Light Science & Application, involved experiments that confirmed OAM's effectiveness in complex environments. The findings suggest potential advancements in areas such as glucose monitoring and secure optical communication systems.
