Area of Science:

Optics and Photonics
Biomedical Imaging
Computational Imaging

Background:

Optical imaging through scattering media is a significant challenge in fields like biological tissue imaging and 'seeing around corners'.
Existing wavefront-shaping methods often require implanted guidestars, coherent illumination, and raster scanning.
Speckle correlation techniques avoid guidestars but are limited to small objects within the memory-effect range.

Purpose of the Study:

To develop a novel, noninvasive, and guidestar-free optical imaging technique.
To overcome the limitations of existing methods, particularly for extended objects and incoherent illumination.
To enable widefield imaging through highly scattering layers without specialized equipment.

Main Methods:

Image-guided wavefront shaping was developed, optimizing image quality metrics blindly.
The technique utilizes incoherent illumination and does not require guidestars or controlled illumination.
Wavefront correction was determined for objects exceeding the memory-effect range.

Main Results:

Demonstrated widefield noninvasive imaging through highly scattering layers.
Successfully imaged extended objects, surpassing the memory-effect limitations.
Showcased the technique's applicability in imaging through multicore fibers.

Conclusions:

Image-guided wavefront shaping offers a versatile and practical solution for optical imaging in scattering media.
This approach eliminates the need for guidestars and complex illumination control.
Paves the way for advanced noninvasive imaging applications in microscopy, endoscopy, and beyond.
