As space missions evolve, SWIR sensors are becoming essential components of multi-spectral imaging systems, delivering unique insights beyond the visible spectrum.

SWIR for Earth Observation – Spectral Requirements

Earth observation applications require a broad spectral range depending on the target. SWIR typically covers wavelengths from:

• 900 nm to 1.7 µm (standard SWIR)
• Up to 2.5 µm for extended SWIR applications

This spectral diversity enables:

• Vegetation and moisture analysis
• Mineral and material identification
• Water content monitoring

The wider the spectral coverage, the more applications it can address, though often at increased system complexity and cost.

SWIR for Firefighting

In the chaos of a fire, every second counts—but smoke can blind even the most experienced firefighters. Traditional visible light cameras struggle in dense smoke, haze, or dust, leaving first responders at a disadvantage when they need clarity the most. Short-Wave Infrared (SWIR) imaging emerges as a game-changing solution, offering unparalleled visibility in the most challenging firefighting environments.

Why Visibility is Critical in Firefighting Environments

Firefighting and emergency response operations take place in highly dynamic and visually complex environments. First responders must operate in conditions where visibility is significantly degraded by:

• Smoke
• Haze
• Water spray
• Dust and airborne particles

These factors reduce contrast and obscure critical scene details, making it difficult to assess situations accurately using conventional visible imaging systems.

SWIR for Firefighting: How SWIR Imaging Enhances Firefighter Situational Awareness

SWIR sensors and cameras provide an additional imaging capability that supports visibility through obscurants and improved scene understanding.

Operating in a reflective imaging regime, SWIR enables:

Improved visibility through smoke vs visible imaging

SWIR wavelengths are less affected by scattering from smoke and airborne particles,allowing better perception of people and structures.

When combined with active illumination, SWIR enables consistent imaging across varying lighting conditions using a single sensor.

Detection of the “seat of the fire” (above 300°C)

While thermal imaging highlights heat signatures, SWIR can contribute to identifying regions of intense combustion while preserving contextual detail.

Structural Information for Safer Operations

Unlike thermal imaging alone, SWIR can reveal edges, structural outlines, and surface features, supporting better interpretation of the environment.

SWIR Firefighting Applications: UAV and Handheld use cases

Situational Awareness

Mounted on UAVs or handheld systems, SWIR imaging supports real-time visibility in smoke-filled environments, helping teams better understand scene layout and hazards.

Search & Rescue

Improved contrast through obscurants can assist in locating individuals in complex environments where visibility is otherwise limited.

Structural Assessment

SWIR imaging can reveal building structure and features, supporting safer navigation and post-fire evaluation.

SWIR for Firefighting vs. Thermal Imaging:

Complementary Technologies for First Responders

The Challenge of Détection and Identifying Small Drones

The rapid adoption of small unmanned aerial systems (UAS) across both commercial and non-cooperative applications has significantly increased the need for effective counter-UAS (C-UAS) solutions.

However, detecting and identifying small drones remains a complex task. These platforms typically present:

• Low radar cross-section (RCS), making them difficult to track
• Low contrast targets, especially against bright or cluttered sky backgrounds
• Operation in complex environments, including urban areas and degraded visibility conditions

While multiple sensing modalities are often combined in C-UAS architectures, achieving reliable identification – not just detection – remains a key challenge.

SWIR Solutions as a Complementary Sensing Layer

SWIR sensors and cameras are increasingly integrated as a complementary imaging layer within C-UAS systems, alongside radar, visible, and thermal technologies.

Operating in a reflective imaging regime, SWIR shares similarities with visible imaging while offering enhanced performance in conditions where standard cameras are limited.

Key Advantages of SWIR Solutions for Counter-UAS

• Better contrast against sky in certain lighting conditions
  SWIR sensors can improve the visibility of drones against bright or hazy skies, where visible imaging often struggles with low contrast.
• Material reflectivity differences
  Drone components such as plastics, composites, and coatings exhibit distinct reflectivity in the SWIR band, enabling improved target differentiation and supporting identification.
• Reduced atmospheric scattering vs visible
  SWIR wavelengths are less affected by haze and atmospheric effects, helping maintain image clarity in degraded environments and at longer stand-off distances.

Extending Capabilities with Gated SWIR Imaging

SWIR solutions can be combined with gated imaging techniques to further enhance detection and identification capabilities.

By leveraging very short exposure times synchronized with active illumination, gated SWIR imaging enables the selective acquisition of reflected light from a defined distance range. This allows the system to suppress background and focus on targets of interest.

This approach supports:

• Day/night operation and all-weather capability using a single sensor
• Improved identification through enhanced target visibility
• Target discrimination in cluttered scenes
• Extended observation range with improved scene clarity

Illustrative example: gated SWIR imaging can reveal the structure of a drone at a distance, improving identification compared to conventional imaging approaches.

Positioning vs Thermal Imaging in Counter-UAS system

Thermal imaging remains a key technology for detecting heat signatures and is often used as a detection channel, or complemented by radar or acoustic solutions in C-UAS systems.

SWIR solutions provide a different type of information:

Thermal imaging

• Detection of heat signatures
• Effective for initial detection
• Limited structural detail in certain scenarios

SWIR imaging

• Captures reflected light
• Provides shape, structure, and reflective features
• Supports improved identification and classification

Rather than replacing thermal imaging, SWIR acts as a complementary layer, particularly valuable when moving from detection to identification.

Supporting Identification in Complex Environments for Counter-UAS

C-UAS systems must operate across a wide range of conditions, including:

• Bright daylight with complex backgrounds
• Degraded visibility due to haze or atmospheric effects
• Long stand-off distances
• Cluttered scene environments

In these scenarios, SWIR solutions help maintain target contrast and clarity, enabling more reliable identification and decision-making.

• Analog
• Conclusion

As counter-UAS requirements continue to evolve, the ability to move beyond detection toward reliable identification is becoming increasingly important.

NIT’s SWIR solutions provide a valuable complementary imaging capability, offering enhanced contrast, reduced sensitivity to atmospheric effects, and access to structural and material information.

By integrating SWIR into multi-sensor architectures, system designers can strengthen identification performance—particularly in scenarios where traditional sensing technologies struggle.
