Key points
- Light scattering was considered a fundamental limit to imaging depth and resolution.
- Spatially shaping the wavefront of incident light allows focusing deep within scattering objects.
- Feedback-based approaches are key to actively controlling wavefronts for focusing.
- This overcomes previous limitations in optical imaging sensitivity and depth.

Abstract
Light scattering was thought to be the fundamental limitation for the depth at which optical imaging methods can retain their resolution and sensitivity. However, it was shown that light can be focused inside even the most strongly scattering objects by spatially shaping the wavefront of the incident light. This review summarizes recently developed feedback-based approaches for focusing light inside and through scattering objects.
