Short-wave Infrared Camera Realizes Real-time Monitoring of Photoelectric Masts of Maritime Cargo Ships

SWIR cameras have a big advantage over other technologies, that is, SWIR cameras can image through glass. For SWIR cameras, there is little need for particularly expensive lenses or housings for harsh environments.

A unique feature of SWIR cameras is that images of faces remain clear in a variety of environments. Another advantage of SWIR imaging is the ability to see through tinted glasses.

Short-wave infrared thermal imagers are less affected by atmospheric scattering, have a strong ability to penetrate fog and smoke, and have a long effective detection distance. The adaptability to climatic conditions and battlefield environments is significantly better than visible light imaging.

Under atmospheric glow night vision conditions, the photon irradiance is mainly distributed in the SWIR band range of 1.0-1.8μm, which makes SWIR night vision imaging have significant inherent advantages compared with visible light night vision imaging.

Multispectral applications of SWIR cameras differ from traditional single broadband imaging techniques. Multispectral and hyperspectral imaging with SWIR cameras combine imaging techniques and spectroscopic measurement techniques. The obtained information includes not only two-dimensional spatial information but also wavelength-related information. The spectral information is distributed, forming a "data cube".

The electro-optical masts of modern submarines require multi-spectral imaging and detection, which is very important and is not currently used for imaging in the near-infrared spectrum.

SWIR imaging is a useful complement to thermal imaging cameras, enhancing the field of view and dealing with severe weather conditions with low visibility. Thermal cameras are good at detecting warm targets against cold backgrounds, while SWIR is good at identifying what the target is, for example (ships, vehicles, or people).

Coastal and seawater details are lost in thermal imaging due to thermal crossover. Shoreline images stand out because SWIR can image reflected light rather than relying on temperature differences, and because SWIR has the ability to penetrate fog, SWIR cameras can capture more detail than visible-light cameras.
