Application: Pixel scale guided mode resonant filter for hyperspectral sensing (Patent ID: US20240176053A1)
The patent filed by Sony Group Corp. describes sensors and systems utilizing a mode resonant filter for hyperspectral sensing. The filter includes a metal grating, a coupling layer, and a metamaterial, with specific details provided for each component. The metal grating is made of aluminum and can be less than 30 nm thick, with various configurations such as grids or parallel lines surrounded by SiO2. The coupling layer is between 20 nm and 40 nm thick, while the metamaterial consists of Si3N4 and TiO2 in cylindrical column structures.
The sensor described in the patent incorporates the mode resonant filter for hyperspectral sensing, along with additional features like a buried SiO2 layer and color filters or micro lenses. An imaging device utilizing this technology includes a pixel array unit with multiple pixels, each equipped with a mode resonant filter consisting of a metamaterial, SiO2 layers, and a metal grating. Overall, the patent focuses on the design and implementation of sensors and systems using advanced filters for hyperspectral imaging, with specific configurations and materials outlined for optimal performance.
