Imaging through scattering media

Focusing or imaging through scattering media is still a big challenge because inhomogeneous media scatter incoming photons for focusing and outgoing photons for observation. Various approachs have been proposed to tackle the scattering issues.

Fast imaging through turbid media is of great interest in fields of astronomical observation and biological imaging. State-of-the-art approachs relies heavily on iterative optimization algorithms or prior charactirazation of scattering media, hence impeding real time imaging scenerio.

Wavefront shaping unlocked many exciting applications related to imaging through scattering media. However, they usually require to have some feedback from the object to observe, typically a guide-star generated by physically labeling the sample or by using ultrasound (that reduced the resolution).
