Exploring a New Optical Approach

CoraLuma is developing a Vis‑SWIR Universal Spectroscopic Core designed to study molecular absorption features across the 400–2600 nm window. This research focuses on fundamental and overtone absorption bands associated with C–H, O–H, and N–H bonds.

Dual‑Stream Signal Processing (Research Concept)

    • Pulsatile (AC) Signal — Intended to isolate transient arterial blood‑volume changes during each cardiac cycle.
    • Static (DC) Baseline — Designed to characterize bulk tissue transmission properties and support mathematical modeling of skin‑related optical effects.

Calibration Framework (Under Development)

CoraLuma is investigating a three‑pillar calibration strategy:

    • Bilateral Transverse Optomechanics — Exploring mechanical stabilization approaches to improve pulsatile signal quality.
    • PID Thermal Stabilization — Designed to reduce emitter/detector drift and improve baseline stability.
    • Multi‑Wavelength Covariance Fusion (MWCF) — A mathematical framework under development to separate tissue‑related optical effects from analyte‑related spectral features.

These methods are experimental and subject to ongoing validation.

Investigational Hardware Platforms

Current Development Platforms

    • Handheld Halogen Diagnostic — A point‑of‑care research platform utilizing a stabilized broadband emitter and an uncooled micro‑spectrometer.
    • Handheld/Arm-Strapped Solid‑State LED Unit — A compact in‑vivo research embodiment using synchronous super‑pulsed LED drive techniques.
    • Clinical In‑Vivo Workstation — A tethered diagnostic hub featuring a TEC‑cooled Extended InGaAs array and a high‑throughput transmission‑grating spectrograph.
    • Clinical In‑Vitro Workstation — A modular laboratory station designed for controlled static microcapillary and microcuvette analysis.

Future Wearable Device Concepts (Forward‑Looking R&D)

    • Arm‑Strapped Array — A high‑density continuous‑monitoring concept incorporating SWIR laser diodes and Volume Bragg Gratings.
    • Wrist‑Worn PIC — A long‑term research concept exploring photonic integration for compact wearable sensing.

These systems represent forward‑looking development objectives and are not yet validated or available for commercial use.
