Enhanced edge detection based on spin hall effect in the uniaxial crystal
Optical analog computing and spatial differentiation have received great attention in many fields. In the field of biology and medicine, it is important to get the high contrast of phase images on a subwavelength scale. Compared with other methods, the optical methods based on the photonic spin Hall...
