POLARIZATION SPECTRAL FILTER, POLARIZATION SPECTRAL FILTER ARRAY, AND POLARIZATION SPECTRAL SENSOR - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18336502 Titled 'POLARIZATION SPECTRAL FILTER, POLARIZATION SPECTRAL FILTER ARRAY, AND POLARIZATION SPECTRAL SENSOR'
Simplified Explanation
The abstract describes a polarization spectral filter that consists of two reflectors facing each other and a grating layer in between. The grating layer contains alternating first and second grating elements arranged perpendicular to the reflectors. The first grating elements are made of a dielectric material with a specific refractive index, while the second grating elements are made of a different dielectric material with a different refractive index.
Original Abstract Submitted
Provided is a polarization spectral filter, including: a first reflector and a second reflector disposed to face each other in a first direction; and a grating layer disposed between the first reflector and the second reflector. The grating layer includes a plurality of first grating elements and a plurality of second grating elements, the plurality of first grating elements and the plurality of second grating elements being alternately arranged in a second direction perpendicular to the first direction. The plurality of first grating elements include a first dielectric material having a first refractive index. The plurality of second grating elements include a second dielectric material having a second refractive index different from the first refractive index.
