SPECTRAL FILTER, IMAGE SENSOR INCLUDING THE SPECTRAL FILTER, AND ELECTRONIC DEVICE INCLUDING THE SPECTRAL FILTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18204139 titled 'SPECTRAL FILTER, IMAGE SENSOR INCLUDING THE SPECTRAL FILTER, AND ELECTRONIC DEVICE INCLUDING THE SPECTRAL FILTER
Simplified Explanation
The abstract describes a spectral filter that consists of multiple first filter arrays, each containing multiple band filters, and multiple second filter arrays placed on top of the first filter arrays, each containing multiple unit filters corresponding to the band filters. Each unit filter includes a first reflecting plate, a second reflecting plate above it, and multiple cavities between the two reflecting plates, with each cavity having a different central wavelength. A dielectric separation layer is placed between the cavity lower layer and the cavity upper layer.
- The patent describes a spectral filter that uses multiple filter arrays and unit filters to selectively transmit specific bands of wavelengths.
- Each unit filter consists of reflecting plates and cavities with different central wavelengths.
- The filter arrays are stacked on top of each other to achieve precise filtering of different wavelength bands.
Potential applications of this technology:
- Optical communication systems: The spectral filter can be used to separate different wavelength channels in optical communication networks.
- Spectroscopy: The filter can be used to isolate specific wavelengths for accurate analysis in spectroscopic applications.
- Imaging systems: By selectively filtering out unwanted wavelengths, the filter can enhance the quality and clarity of images.
Problems solved by this technology:
- Precise wavelength selection: The spectral filter allows for the precise filtering of specific wavelength bands, enabling accurate separation and analysis of different wavelengths.
- Compact design: The use of stacked filter arrays and unit filters allows for a compact and efficient design, reducing the size and complexity of optical systems.
Benefits of this technology:
- Improved signal-to-noise ratio: By selectively filtering out unwanted wavelengths, the filter improves the signal-to-noise ratio in optical systems, leading to better performance.
- Enhanced spectral resolution: The precise filtering capability of the filter allows for improved spectral resolution in applications such as spectroscopy.
- Compact and versatile design: The stacked filter arrays and unit filters provide a compact and versatile solution for wavelength selection, making it suitable for various optical systems and applications.
