Abstract

We explore the potential of using shaped light carrying orbital angular momentum (OAM) in diagnosis of cells and biological tissues. So far, the spin angular momentum (SAM) of light has been employed extensively in various diagnostic applications [1,2]. Since recently much attention has been drawn to the laser beams carrying OAM. It has been demonstrated that this, so-called, complex structured light is able penetrate deeper into the turbid tissue-like scattering medium providing higher visibility contrast [3,4]. Nevertheless, the potential of OAM for practical biomedical diagnosis and tissue characterization is far from being fully explored.
