We propose a novel scheme for designing and generating kaleidoscope-structured vector optical fields (KS-VOFs) by analogy with the principle of multiple mirror reflection in a kaleidoscope. For KS-VOFs with symmetric polarization states. we show the symmetry properties of the focal fields with various shapes for different applications. The redistributing symmetric local spin angular m... https://halohealthcarers.shop/product-category/cervical-collars/
