Non-diffracting beams for label-free imaging through turbid media

We propose a new method to image through dynamically changing turbid media based on the scanning of nondiffractive laser beams. We use computer-generated holograms to create Airy beams and compare quantitatively the characteristics of their propagation in clear and turbid media. Imaging contrast is achieved by relative reflection of the scanned beams from the imaged surface. We implement our method to demonstrate experimentally our ability to image a chromium surface on a glass slide through 270 mu m of highly scattering milk/water mixtures with a resolution of several microns.
