the application fields and practical cases of SWIR cameras

SWIR imaging has a major advantage over other techniques, namely its ability to image through glass. For SWIR cameras, special expensive lenses or housings for harsh environments are almost unnecessary. This allows them to be used in a wide variety of applications and industries. Below are some of the application fields and practical cases of SWIR cameras.

Application field

Semiconductor Industry

(1) Packaging - crushing equipment testing

(2) Material and circuit inspection

(3) Imaging of circuit defects and failures

(4) Photovoltaic inspection

Ophthalmology

(1) retinal examination

(2) Composite color optical coherence tomography

Dermatology

(1) Skin hydration

(2) Melanoma ID

Dentistry

(1) Enamel inspection between neighbors

(2) Enamel inspection of occlusion

(3) Surface inspection

Agriculture

(1) Irrigation planning - checking soil moisture

(2) Production inspection - loss assessment and quality packing

(3) Meat Inspection - contamination detection

Fiber inspection

(1) Cladding inspection-complex fiber circuit debugging

(2) Telecommunications and laser optical bench detection

National defense

(1) Night vision - persistent/staring passive application target acquisition

(2) Search and rescue - infrared signals for day/night visibility

Actual case

1. Identify man-made materials

Since man-made materials have a unique way of reflecting at short-wave infrared wavelengths, this will help distinguish materials that look similar to the naked eye in the visible spectrum. Make it present a more specific type distinction in the image.

2. Fire fighting

Many substances have specific emissivity and absorption properties in the short-wave infrared band, such as snow, ice, various rocks, and man-made materials. It is these properties that we use to identify these substances during image analysis. SWIR can even penetrate some smoke to identify the point of ignition.

Whether forest fires or wildfires, once out of control can cause devastating blows to local residents and natural resources, fast and effective fire detection is essential to protect infrastructure and ensure the safety of residents. Fires may seem easy to spot but are often visually impaired.

For example, smoke can obstruct a firefighter's sight on the ground or in the air. On the left, it's easy to see where the smoke is coming from, but it's hard to tell the ground fire along the fence line.

3. Discovery of mineral deposits

Short-wave infrared wavelengths make it possible to accurately identify minerals. Depending on the mineral content, different components absorb the number of light waves, resulting in different reflectances.

Application of short-wave infrared images in the field of geology. According to the absorption of light waves by different minerals, different spectral lengths are reflected, and substances containing l-OH, Mg-OH, Fe-OH, Si-OH, carbonate, ammonium, and sulfate ion groups are detected according to the wavelength.

In order to determine which ore these mining areas have. Geologists and miners often spend millions of dollars in the exploration phase to find potential mining areas, and the use of short-wave infrared imagery can reduce costs and improve efficiency by narrowing down potential mining areas before planning on-site inspections.

In addition to these common applications, SWIR imaging technology also has an excellent performance in other fields. If you want to know more information after reading the above, JAVOL is happy to provide you with professional knowledge.
