High-speed wavefront shaping offers improved imaging in tissues

September 16, 2019

Scattering of light as it passes through tissue is a significant barrier to imaging cleanly in biological media such as blood and skin.
Wavefront shaping (WFS) is known to be a possible solution, in which the scattering that occurs as coherent light passes through tissue is tackled through careful control of the incident wavefront first entering the sample.

If the incident wavefront can be shaped and controlled at timescales shorter than that of the dynamic scattering caused by the media, through a suitable adaptive feedback process, then the scattering distortions can be compensated for and an enhanced intensity of light created at a desired point within the target.
