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 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: Apparatus for and a method of rotating microscopic objects uses a beam of electromagnetic radiation. A microscopic, non-circularly symmetric distribution of electro-magnetic radiation is projected on to a region containing an object to be rotated so as to cause photons in the beam to refract around the objects. Rotating means then rotate that distribution and so rotate the objects. The distribution may be formed on the interference pattern between a beam having a Laguerre-Gaussian wave fronts and either a plane wave or a further Laguerre-Gaussian beam of opposite helicity.
