In this movie, the polarized optical micrograph of the q = 1/2 FLC q-plate switches between two states under the external electric field with opposite polarities. On the right side of the frame, the ...

The performance of the LESI method proposed in this study was compared with that of recently reported edge detection schemes. (ESI: edge-sensitive single-pixel imaging. LESI: ESI with Laplacian ...

Introduction to computer and biological vision systems, image formation, edge detection, image segmentation, texture, representation and analysis of two-dimensional geometric structures, and ...

When a beam is reflected (or refracted) at optical interface or propagating through an inhomogeneous medium, photons with opposite spin angular momenta will separate with each other, resulting in a ...
