What Are the Applications of SWIR Cameras in the Security Field?

the outstanding performance of SWIR cameras in the field of security

As short-wave infrared is gradually becoming well-known to everyone, the degree of attention to its application fields is gradually increasing. SWIR cameras have outstanding performance in the following applications in the security field, and they have also played an irreplaceable role

Maritime field

The photoelectric masts of modern submarines require multi-spectral imaging and detection. For example, visible-light imaging is usually unable to observe the target through haze, dust, and smoke, but short-wave infrared is very easy to achieve. In this case, short-wave infrared cameras have better imaging results.

An important difference between short-wave infrared and medium- and long-wave infrared is that it uses reflected light for imaging instead of radiant thermal imaging. Long-wave cameras cannot see important features of sea targets, such as the names of ships and characteristics of ships. Short-wave infrared cameras can provide assistance here.

Shortwave infrared uses reflected light for imaging. Because the wavelength is longer than visible light, it is easier to pass through haze, fog, and high humidity at sea, and you can see the name of the ship.

Port and Haiphong

Sometimes, the thermal contrast of a scene may be too low. For example, during the day, the temperature of the landing zone (radiation rate) maybe twice the temperature of the surrounding lawn. In the marine environment, when various objects are immersed in water for a long time, they have the same temperature as the water.

Passive or active short-wave infrared imaging can improve contrast in a shorter wavelength range and enhance image details. Shortwave infrared is based on reflected light imaging and has the characteristics of fog penetration, so the coastline image can stand out and capture more details than visible light cameras.

Security defense of critical infrastructure

In any surveillance, safety, and security work, clear visibility is particularly important. At this time, the more "eyes" you have, the clearer you can see.

Peripheral security defense of critical infrastructure is a typical application case. An effective foreign object intrusion detection system uses a variety of technologies to increase the rapid detection rate under a variety of atmospheric and light conditions and reduce the false alarm rate. For common weather conditions such as rain, fog, and haze, visible light monitoring is almost "blind."

Forest fire

The smoke from forest fires reduces visibility, which is detrimental to rescue operations and can cause major economic losses. Unlike the large-area pan-white heat map in the long-wave infrared forest fire image, short-wave infrared can not only penetrate the smoke but also accurately find the fire point, thereby greatly reducing the search range of the fire point.


With the advancement of technology and the enhancement of the professional quality of pilots and crews, the safety of aircraft has improved significantly to this day, and darkness, fog, and rain are the main enemies of safe flight.

Integrating a short-wave infrared sensing system in the aircraft's assisted landing system allows the pilot to penetrate dark and severe weather conditions to obtain an infrared view of the aircraft's surrounding environment.

InGaAs short-wave infrared cameras provide excellent fog-through imaging capabilities in the key spectral range of 900 to 1700 nm. Compared with many existing infrared thermal imaging systems, short-wave infrared cameras do not require a complex and expensive low-temperature cooling system, which greatly improves the reliability of the system and the flexibility of installation.

SWIR imaging camera uses the latest advanced InGaAs sensor, based on 640 x 512, 15μm InGaAs sensor (0.9μm to 1.7μm), has the advantages of small size, lightweight, low power consumption, suitable for a wide range of machine vision applications. It is flexible in installation and configuration, has excellent short-wave infrared imaging performance, and is easy to integrate with various optoelectronic systems.
