SOLID-STATE IMAGING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18293044 titled 'SOLID-STATE IMAGING DEVICE
The abstract describes a solid-state imaging device with a metasurface structure that can concentrate light on the center of each pixel, even when the light enters obliquely.
- The device includes a pixel region with multiple pixels and a polarization control element above the pixel region, consisting of microstructures arranged parallel to the incidence surface.
- Each pixel has microstructures that concentrate light in a specific polarization direction, with the position of the microstructures within the pixel determining their effectiveness.
Potential Applications: - High-resolution imaging systems - Optical communication devices - Medical imaging equipment
Problems Solved: - Improved light condensation on pixel centers - Enhanced image quality in various lighting conditions
Benefits: - Higher image resolution - Better performance in low-light environments - Increased efficiency in light utilization
Commercial Applications: The technology could be utilized in the development of advanced cameras, medical imaging devices, and optical sensors for various industries.
Questions about the technology: 1. How does the metasurface structure improve light condensation on pixel centers? 2. What are the potential challenges in implementing this technology in commercial imaging devices?
Original Abstract Submitted
Provided is a solid-state imaging device having a metasurface structure with which light can be condensed on the center of each pixel even if the light obliquely enters a pixel region. A solid-state imaging device according to the present embodiment includes a pixel region that includes multiple pixels, and a polarization control element that is disposed above an incidence surface of the pixel region on which incident light is incident and that includes multiple microstructures which are two-dimensionally arranged in substantially parallel with the incidence surface. Of the multiple microstructures corresponding to a first pixel included in the pixel region, a first microstructure has a maximum length in a first polarization direction of the incident light, and a position of the first microstructure in the first pixel depends on the distance from the center of the pixel region to the first pixel.
