Towards polarization steganography
Valeria Tena-Piñon, Atefeh Akbarpour, Przemyslaw Litwin +6
We propose and experimentally demonstrate a polarization--based steganographic scheme using partially polarized vector beams. In our approach, the spatially dependent polarization…
Accurate and Noise-Robust Wavefront Reconstruction with an Optical Vortex Wavefront Sensor
Magdalena Åukowicz, Aleksandra Korzeniewska, Kamil Kalinowski +3
The term wavefront sensor refers to the entire class of devices capable of measuring the optical wavefront of the incoming beam. Although numerous solutions have been proposed so f…
Optical vortex trajectories as probes for wavefront aberrations
Aleksandra K. Korzeniewska, Magdalena Lukowicz, Kamil Kalinowski +2
Phase singularities, due to their high sensitivity to phase disturbances, are a promising tool for wavefront retrieval. Several methods have been proposed to exploit this property,…
