Core Technology & Innovations

AeroPhotonix LLC develops next-generation intelligent photonic sensing platforms designed to overcome the fundamental limitations of conventional aerosol and particulate monitoring systems. Our technology integrates advanced optical physics, polarization-resolved scattering, and embedded artificial intelligence into a unified sensing architecture capable of delivering high-fidelity particle characterization in real time.

Unlike traditional instruments that rely on narrow-angle intensity measurements or bulk mass concentration estimates, AeroPhotonix systems retrieve full angular phase functions, polarization signatures, and morphology-sensitive optical parameters. This enables deeper insight into particle size, shape, refractive index, and composition transforming particulate monitoring from simple detection into intelligent classification.

Elastic Light Scattering Systems (Ultra-Wide Angular Coverage (0.32°–179°))

Our elastic light scattering architecture provides one of the broadest angular coverage ranges available, capturing both the forward scattering peak and near-backscatter region. This enables:

• High-accuracy particle size retrieval

• Improved morphology sensitivity

• Enhanced refractive index estimation

• Full phase-function (F11) reconstruction

By measuring nearly the complete scattering profile, AeroPhotonix overcomes the narrow-angle limitations of legacy nephelometers and PM sensors.

Advanced Polar Nephelometry (Phase Function (F11) + Linear Depolarization Ratio (LDR) + Degree of Linear Polarization (DoLP) + Machine Learning)

Our polarization-resolved nephelometry platform simultaneously measures:

• Angular phase function (F11)

• Linear depolarization ratio (LDR)

• Degree of linear polarization (DoLP)

These parameters enable shape-sensitive particle classification, distinguishing:

• Dust vs soot

• Spherical droplets vs irregular particles

• Biological vs non-biological aerosols

Integrated machine learning algorithms further enhance inversion accuracy and enable real-time intelligent interpretation.

AI-Driven Inversion & Intelligent Analytics

AeroPhotonix embeds advanced AI and machine learning directly into the sensing architecture, enabling:

• Real-time particle size retrieval

• Automated particle classification

• Multi-modal data fusion

• Adaptive noise suppression

• Reduced calibration drift

Unlike traditional lookup-table approaches, our AI-enhanced inversion continuously improves performance across varying environmental conditions.

Ambient Aerosol & Bioaerosol Detection (Fluorescence (LIF) + Scattering + AI)

By integrating laser-induced fluorescence (LIF) with elastic scattering and polarization metrics, our systems enhance biological discrimination and reduce false positives. This enables applications in:

• Public health monitoring

• Biosecurity and defense

• Environmental surveillance

Multi-Modal Optical Sensing Architecture

AeroPhotonix integrates multiple complementary optical techniques into a unified platform:

• Static light scattering

• Polarization-resolved detection

• Digital holography

• Fluorescence spectroscopy

• AI-based data analytics

This vertically integrated ecosystem from particle generation and optical measurement to algorithmic inversion delivers a scalable, deployable, and future-ready sensing solution.

AeroPhotonix does not simply build sensors. We build intelligent optical systems capable of retrieving microphysical, morphological, and radiative properties of airborne particles in real time across laboratory, ground-based, airborne, and balloon-deployable platforms. By combining advanced photonics with embedded AI, we move beyond bulk PM concentration toward true optical intelligence.
