What Are Some Examples of Fusion Night Vision Devices?

Fusion night vision technology represents a significant advancement in optoelectronic devices by combining image intensification (I2) and thermal imaging to enhance visibility in varied lighting conditions. These devices offer superior situational awareness by merging the benefits of both technologies, enabling users to see clearly in darkness, through smoke, or in challenging environments. Here, we explore notable examples of fusion night vision devices that illustrate the evolution and capabilities of this technology.

1. AN/PSQ-20 Enhanced Night Vision Goggle (ENVG)

The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) is one of the pioneering fusion systems developed to integrate image intensification and thermal imaging.

  • Features: This device combines a 16-mm I2 tube with a 320 x 240 pixel microbolometer thermal imager. It was designed to replace the older AN/PVS-7 and AN/PVS-14 night vision goggles.
  • Deployment: Fielded in 2009 as the ENVG I, the ENVG faced limitations in its initial deployment due to its weight and rapid battery drain.
  • Purpose: It aimed to provide a comprehensive view by integrating thermal and image intensification technologies, although it saw limited use due to its early-stage design constraints.

2. AN/PSQ-20A Spiral Enhanced Night Vision Goggle (SENVG)

The AN/PSQ-20A Spiral Enhanced Night Vision Goggle (SENVG) was developed under a 2010 Department of Defense contract to meet the US Army’s ENVG II requirements.

  • Features: It incorporated a color microdisplay and used a separate battery pack, which allowed for both helmet-mounted and hand-held use.
  • Advancements: The SENVG improved upon its predecessor by enhancing the user’s ability to switch between night vision modes and incorporating a color display for better image clarity.
  • Deployment: Designed to overcome the drawbacks of earlier models, the SENVG provided a more user-friendly experience with extended operational flexibility.

3. ENVG-B (Enhanced Night Vision Goggle-Binocular)

The ENVG-B represents the latest generation of fusion goggles and includes the AN/PSQ-42 and AN/PSQ-44 models.

  • Features: This device offers separate I2 and thermal channels for each eye, significantly improving depth perception and situational awareness. Users can select between I2, thermal, and fused viewing modes.
  • Technological Advancement: The ENVG-B provides enhanced visual depth and the ability to toggle between different imaging modes, making it a versatile tool for modern military and tactical operations.
  • Deployment: The latest models in the ENVG series, the ENVG-B goggles, represent the cutting edge of night vision technology with their ability to provide clear and detailed images across various conditions.

4. FusionSight by Bertin Technologies

FusionSight by Bertin Technologies is a notable lightweight monocular fusion device designed for both infantry and special forces use.

  • Features: The device combines visible and thermal imaging sensors, offering both separate and fused viewing modes. It also includes digital recording capabilities, enhancing its utility in tactical situations.
  • Advantages: FusionSight provides users with the flexibility to switch between day and night vision modes while also recording their observations. This makes it a valuable tool for real-time analysis and documentation in the field.
  • Deployment: Its design caters to modern military needs, providing a compact and versatile option for enhanced visibility and operational effectiveness.

5. SENTINEL-CNV by Adams Industries

The SENTINEL-CNV by Adams Industries is an advanced night vision device that employs proprietary modifications to I2 tubes to enhance color contrast.

  • Features: It is optimized to deliver more lifelike color under moderate illumination and improved contrast overall.
  • Deployment: Deployed by US Special Forces since 2003, the SENTINEL-CNV has been recognized for its ability to provide superior color fidelity and contrast in low-light conditions.
  • Advantages: This device addresses the challenge of limited color representation in traditional night vision systems, offering a more realistic view of the environment.

Conclusion

Fusion night vision devices are at the forefront of technological innovation, combining the strengths of image intensification and thermal imaging to offer superior visibility and situational awareness. Each example, from the AN/PSQ-20 to the SENTINEL-CNV, demonstrates unique advancements and features tailored to various operational needs.

As the technology continues to evolve, these devices are becoming increasingly compact, capable, and widely adopted by military, law enforcement, and specialized civilian users. The integration of both imaging technologies ensures a more comprehensive view of the environment, enhancing the ability to navigate and respond effectively in diverse conditions.
