The novel distortion matrix approach enables detection of micro-calcifications in breast cancer. These precursors of breast cancer are impossible to detect in the conventional ultrasound image.

Measuring the entire reflection matrix is time-consuming and vulnerable to external perturbations because a large number of interferometric images for all accessible input illumination fields ...

With the combination of reflection matrix measurement, decomposition of time reversal, and wavefront shaping technology, we have presented a systematic method in the investigation of (1) photons ...

Then, they obtained a compressed reflection matrix by taking a much smaller number of speckle images than previously required, which reduced the matrix acquisition time by nearly 100 times.
