Non-diffracting beams for label-free imaging through turbid media
Harel Nagar , Dr. Yael Roichman
Physical chemistry
In recent years many imaging techniques were developed in order to image through turbid media. However, imaging through highly scattering media is still very challenging. We present a new method to image through dynamically changing turbid media based on scanning of non-diffractive laser beams. By using computer generated holograms, we create Airy beams and exploit their "self-healing" properties to enhance our imaging ability through milk. In this talk, we demostrate experimentally our ability to perform label free imaging of a chromium surface on a glass slide through 270µm of highly scattering milk/water mixtures with a resolution of several microns.
