CONTROLLING LIGHT TRANSMISSION THROUGH A MEDIUM |
摘要 |
A method for use in controlling light transmission through a medium comprises transmitting light from a single spatial portion of an input optical field through the medium to create an output optical field, superposing the output optical field with a reference optical field to create an optical interference field, detecting an intensity of a spatial portion of a polarisation component of the optical interference field and using the detected intensity to determine a value of an optical field amplitude and a value 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 polarisation states of the transmitted light entering the medium. The method may be used in the control of the transmission of light through a medium which is randomising in amplitude, phase and/or polarisation. The method may be used in the control of the transmission of light through a multi-mode fibre. The method may be used for beam shaping, optical trapping and/or optical manipulation. |
