Metasurfaces are similar to diffractive optics.
Engineered elements sub-wavelength spaced arrays of phase shifting materials for some effect.
All electro-magnetic waves have spin, or polarization. As the light passes through a grating, it moves only in one orientation, and is now considered polarized.
What are metasurfaces good for?
Replacing bulk optics
“Multifunctional” metasurfaces -> metasurfaces that have multiple functions that are accessed through degrees of freedom.
Examples below:
Wavelength
Incident Angle

Why we use aurora technology?

Typical optical systems are bulky, with multiple components. |
Aurora uses metaoptic technology to capture more polarization data in a single image versus the 16 required for other methods. The above image explains the differences. |

Metapotical Innovation
What is a Metaoptic Lens?
Unlike traditional polarimetry systems, which require multiple optical elements or lenses to measure different polarization states, Aurora’s met.
Mueller Matrix Analysis
The Mueller matrix provides more comprehensive diagnostic data than the traditional 4-element Stokes polarimeters by capturing changes in polarization related to diattenuation, roughness, and birefringence.
logical Neural network mention
Traditional neural networks often act as "black boxes," making it difficult to understand their decision-making. In contrast, LNNs use rule-based logic, providing clear, interpretable outputs.This is especially important in biomedical applications, where Aurora's 4x4 Mueller matrix—normally unreadable to non-physicists—can now be easily interpreted by physicians. By translating complex polarization data into actionable insights, Aurora ensures that healthcare professionals can confidently understand and trust the diagnostic results, improving both decision-making and patient outcomes.
Applications in Cancer Detection
Enhanced Cancer Detection
Aurora can differentiate between melanoma, squamous, and basal cell carcinomas with more accuracy.
Potential for Space Use
Astronauts exhibit 10x the risk of skin cancer. Auroras portable design aligns it with NASA’s goal of safeguarding astronauts from increased UV exposure during space missions.
