Title:
OPTICAL MEASUREMENT APPARATUS INCLUDING UNIVERSAL METASURFACE, AND OPTICAL MEASUREMENT METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/173240
Kind Code:
A2
Abstract:
An optical measurement apparatus, according to one aspect of the present invention, comprises: a universal metasurface on which light is incident; a polarizations sensor which measures the polarization state of light passing through the universal metasurface; and a control unit which collects a quantitative differential interference contrast (QDIC) image for x polarization and a QDIC image for y polarization of the incident light collected by the polarization sensor, and a quantitative relative phase (QRP) image indicating the relative phase difference between the x polarization and the y polarization, and calculates the intensity, phase, or polarization information about the incident light.
