Imaging through Turbid Media
A major limitation of conventional microscopes is the penetration depth in turbid media (e.g tissue, thick cells). It is known that turbid media scatter the incoming light, resulting in a messy image after the sample. But there is clever way to undo the effect of scattering medium by simply modulating the incoming light using a Spatial Light Modulator(SLM) or an equivalent device to adjust the wavefront.
