Optical technologies have been increasingly utilized in biomedicine, including diagnosis, therapy, and surgery. In almost all of these applications, photons need to propagate some distance in tissue. Therefore, the capability of f

Despite the unique advantages of optical microscopy for molecular specific high resolution imaging of living structure in both space and time, current applications are mostly limited to research settings. This is due to the aberra

Visual perception of humans penetrating turbid medium is hampered by scattering. Various techniques have been prompted recently to recover optical imaging through turbid materials. Among them, speckle correlation based on deconvol

Coherent optical control within or through scattering media via wavefront shaping has seen broad applications since its invention around 2007. Wavefront shaping is aimed at overcoming the strong scattering, featured by random inte

While propagating inside the strongly scattering biological tissue, photons lose their incident directions beyond one transport mean free path (TMFP, ~1 millimeter (mm)), which makes it challenging to achieve optical focusing or c

We observed a phenomenon that different scattering components have different decorrelation time. Based on decorrelation time difference, we proposed a method to image an object hidden behind a turbid medium in a reflection mode. I

By manipulating the phase map of a wavefront of light using a spatial light modulator, the scattered light can be sharply focused on a specific target. Several iterative optimization algorithms for obtaining the optimum phase map

Two-photon microscopy normally suffers from the scattering of the tissue in biological imaging. Multidither coherent optical adaptive technique (COAT) can correct the scattered wavefront in parallel. However, the determination of

Feedback-based wavefront shaping focuses light through scattering media by employing phase optimization algorithms. Genetic algorithms (GAs), inspired by the process of natural selection, are well suited for phase optimization in

Melanoma, characterized by high mortality, rapid development and accompanied with angiogenesis is the most typical malignant tumor in skin cancer. Hence, the detection of blood vessels is of much significance. The early vascular n

Changes of the blood vessels and collagen are associated with the development of abnormal cervical cells. Recently, optical coherence tomography and Mueller polarization images were used to provide information regarding the presen

Wavefront shaping (WFS) techniques have been used as a powerful tool to control light propagation in complex media, including multimode fibers. In this paper, we propose a new application of WFS for multimode fiber-based sensors.
