    Abstract: Methods for controlling light transmission through a medium by transmitting light from a single spatial portion of an input optical field through the medium creating an output optical field, superposing the output optical field with a reference optical field creating an optical interference field, detecting an intensity of a spatial portion of a polarization component of the optical interference field and using the detected intensity to determine a value of an optical field amplitude and of an optical field phase for each of a plurality of spatial portions of the input optical field and for each of first and second orthogonal input polarization states of transmitted light entering the medium. The method may be used in the control of the transmission of light 1) through a medium, which is randomizing in amplitude, phase and/or polarization or 2) through a multi-mode fiber or for beam shaping, optical trapping and/or optical manipulation.

    Abstract: A cell permeabilizing micro fluidic system for permeabilizing one or more cells in a fluid flow. The system has a micro fluidic channel for channeling at least one cell in a fluid flow and an optical source for generating a beam of light for permeabilizing the at least one cell, wherein the channel and the source are arranged so that the light beam and fluid flow are collinear in a permeabilization part of the channel and cells are permeabilized within the permeabilization part.

    Abstract: A method and apparatus for clearing an optical channel for transmitting data through free space between a first and second location includes a light beam, wherein the light beam has a spatially and/or time-dependent modulated intensity profile, and is substantially collimated so that the intensity profile is conserved over a specified distance of operation. The light beam includes a cross-sectional profile having regions of low and high intensity, portions of which are provided for the transmission of an optical data signal. A light source wavelength and intensity are selected for types of obscurant particles having optical properties whereby the radiation pressure acts on the particles, and the particles may then be either attracted into or repelled from portions of the spatially modulated optical beam, leaving certain portions of the optical channel beam absent of obscurant particles, thereby enabling transmission of optical data through the cleared optical channel with low attenuation.

    Abstract: An optical coherence tomography system comprising a light source (a) and a probe (e) that has a window at a front facing end. The window has an inner face (i) that has an anti-reflection surface and allows light from the source to pass through it, and an outer face (j) that reflects some of the light from the source and transmits some of the light to and from the sample (k). The reflected light acts as a reference.
