Wavefront shaping makes it possible to form a focus through opaque scattering materials. In some cases, this focus may be scanned over a small distance using the optical memory effect. However, in many cases of interest, the optical memory effect has a limited range or is even too small to be measured. In such cases, one often resorts to measuring the full transmission matrix (TM) of the sample to completely control the light transmission. However, this process is time-consuming and may not… Expand

Compressively sampling the optical transmission matrix of a multimode fibre
This work explores how measurement requirements of the optical transmission matrix can be relaxed using the framework of compressive sensing, in which the incorporation of prior information enables accurate estimation from fewer measurements than the dimensionality of the TM the authors aim to reconstruct.

Phase control algorithms for focusing light through turbid media
Light propagation in materials with microscopic inhomogeneities is affected by scattering. In scattering materials, such as powders, disordered metamaterials or biological tissue, multiple scatteringExpand
Transmission matrix of a scattering medium and its applications in biophotonics.
This review paper introduces two major applications of the transmission matrix: enhancing light energy delivery and imaging through scattering media and solved matrix inversion problem to reconstruct an object image from the distorted image by the scattering media. Expand

Controlling light propagation across scattering media by wavefront shaping holds great promise for a wide range of communications and imaging applications. But, finding the right shape for theExpand
Measuring large optical transmission matrices of disordered media.
The singular value spectrum of the TM is investigated in order to detect evidence of open transmission channels, predicted by random-matrix theory, and the results comport with theoretical expectations, given the experimental limitations of the system. Expand

Diffraction-limited imaging through complex scattering media is a long-sought-after goal with important applications in biomedical research. In recent years, high-resolution wavefront shaping hasExpand
Measuring the transmission matrix in optics: an approach to the study and control of light propagation in disordered media.
The transmission matrix of a thick random scattering sample is determined and it is shown that this matrix exhibits statistical properties in good agreement with random matrix theory and allows light focusing and imaging through the random medium. Expand
Image transmission through an opaque material.
This work shows that it is possible to measure the complex mesoscopic optical transmission channels that allow light to traverse through such an opaque medium and optimally exploit those channels to coherently transmit and recover an arbitrary image with a high fidelity, independently of the complexity of the propagation.

Controlling waves in space and time for imaging and focusing in complex media
In complex media such as white paint and biological tissue, light encounters nanoscale refractive-index inhomogeneities that cause multiple scattering. Such scattering is usually seen as anExpand
Generalized optical memory effect
The optical memory effect is a well-known type of tilt/tilt wave correlation that is observed in coherent fields, allowing control over scattered light through thin and diffusive materials. Here weExpand
Optimal control of light propagation through multiple-scattering media in the presence of noise.
The model concludes that the control of coherent light propagation through a multiple-scattering medium is only determined by the number of photoelectrons detected per optimized segment. Expand
