SPECTRAL FILTER, AND IMAGE SENSOR AND ELECTRONIC DEVICE INCLUDING THE SPECTRAL FILTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17880187 titled 'SPECTRAL FILTER, AND IMAGE SENSOR AND ELECTRONIC DEVICE INCLUDING THE SPECTRAL FILTER
Simplified Explanation
The abstract describes a spectral filter that is used in an image sensor and electronic device. The spectral filter consists of multiple layers and patterns that allow for filtering of different center wavelengths.
- The spectral filter includes a first metal reflective layer.
- Above the first metal reflective layer, there is a second metal reflective layer.
- Between these two layers, there are multiple cavities that contain patterns corresponding to different center wavelengths.
- Below the first metal reflective layer, there are multiple lower pattern films that also contain patterns corresponding to different center wavelengths.
Potential applications of this technology:
- Image sensors in digital cameras and smartphones.
- Spectral analysis in scientific research and medical imaging.
- Optical filters in various imaging and sensing devices.
Problems solved by this technology:
- Enables precise filtering of different center wavelengths.
- Provides a compact and efficient solution for spectral filtering.
- Allows for customization and flexibility in filtering different wavelengths.
Benefits of this technology:
- Improved image quality and accuracy in capturing specific wavelengths.
- Compact design allows for integration into small electronic devices.
- Customizable filters provide versatility for different applications.
