Title:
OPTICAL ELEMENT, OPTICAL CELL, ANALYSIS DEVICE, AND OPTICAL ELEMENT DESIGN METHOD
Document Type and Number:
WIPO Patent Application WO/2023/195345
Kind Code:
A1
Abstract:
This optical element comprises a plurality of columnar bodies formed by a material having a prescribed dielectric constant and disposed on a flat surface of a transparent substrate through which light is transmitted in a matrix pattern. Each of the columnar bodies is configured to: perform phase adjustment on output light which is the result of the foregoing light which was input being transmitted and output, such phase adjustment being on the basis of the dielectric constant, the cross-sectional shape of the columnar body in a direction parallel to the flat surface, and the length of the columnar body in a normal direction which is the direction normal to the flat surface; and to adjust deflection characteristics in the normal direction, lens characteristics that condense light in the normal direction, and polarization characteristics in the normal direction, such that the output light having desired polarization characteristics is outputted.
