Controlling the propagation and interaction of light in complex media has sparked major interest in the past few years. Unfortunately, spatial light modulation devices suffer from limited speed, which precludes real-time applications such as imaging

We achieve full focusing through complex media in 2.4ms using a 1D phase modulator. We study the behavior of enhancement and focus shape, especially with regard to memory effect for a 1d modulation.

Focusing inside scattering media is a challenging task with a variety of applications in biomedicine. State of the art methods mostly require invasive feedback inside or behind the sample, limiting practical use. We present a technique for dynamic co

We present a technique for focusing inside scattering media that combines optical-coherence-tomography (OCT) and wave-front-shaping (WFS). We use OCT as a non-invasive feedback for WFS optimization of a separate penetrating laser, based on light-indu

We demonstrate the capabilities of a high-speed phase modulation system based on a digital micromirror device. We use the system to focus light through dynamic scattering materials. We demonstrate up to three orders of magnitude speed improvement res

We present a reconfigurable high-speed phase modulation system based on a digital light projector for application in endoscopic multimode fibers. A custom driver and FPGA reduce data transfer enabling adaptive wavefront shaping at kilohertz rates.

The optical imaging depth in biological materials is limited by the scattering of light in tissue. New methods which control light propagation through scattering media have been introduced with the potential to overcome the scattering of light in bio

We control light propagation through highly scattering media by an adaptive holographic technique. An FPGA-controlled deformable mirror device generates phase optimized wavefronts at a high rate that approaches the decorrelation time of living biolog

Multimode optical fibers are attractive for biomedical and sensing applications because they possess a small cross section and can bend over small radii of curvature. However, mode phase-velocity dispersion and random mode coupling change with bendin
