The proposed signal path
Visible or infrared light interacts with a sample. The resulting optical response is detected and compared with a reference. Interpretation then seeks to connect changes in the spectrum with chemical information.
- 01
Illuminate
Introduce light under controlled conditions.
- 02
Interact
Observe how the sample changes the optical response.
- 03
Detect
Capture a signal suitable for reference comparison.
- 04
Interpret
Evaluate spectral information within a calibration model.
Photonics and signal interpretation
Our proposed architecture adds a reprogrammable analog neuromorphic processor, software support and connectivity. These are architectural directions, not yet an integrated system.
What integration needs to resolve
Calibration
Define the reference, operating conditions and sensitivity to variations in the sample.
Optical coupling
Characterize the path between the light source, sample and detector in a physical setup.
System constraints
Establish power, packaging, stability and signal-processing requirements through experiments.
Where AIFIELD contributes
For this sensing direction we designed a photonic glucose chip in AIFIELD. The AIFIELD pages explain how it was designed; the ArtiSense validation pages explain what measurement still has to show. A simulated design is one input to that work.
