The invention discloses a super-surface
color vector complex amplitude holographic element, which comprises a bimetallic
nanorod unit structure with adjustable in-plane rotation angles and in-plane displacement, wherein an aluminum-
silicon dioxide-aluminum super-structure
grating structure generates a polarization-selective type
diffraction efficiency enhancement effect in a visible light range; asum of in-plane displacement of two
metal nanorods in the
unit structure and
diffraction phase information are in a
linear modulation relationship, a difference between the rotation angles of the twometal nanorods and a
diffraction light amplitude are in a
sinusoidal modulation relationship, and a sum of the rotation angles of the two
metal nanorods and a diffraction light polarization directionare in a
linear modulation relationship; and a color holographic method is implemented on diffraction level by utilizing the
phase displacement based on inherent dispersion of the super-structure
grating. The super-surface
color vector complex amplitude holographic element disclosed by the invention has the advantages of low requirements for preparation control precision, simple structure, high degree of control freedom and the like, and has powerful functions of simultaneously controlling four parameters of
light wave phase, polarization, amplitude and frequency.
