What Are the Principles and Characteristics of Shortwave Infrared Imaging?

Short-wave infrared imaging uses photoelectric technology to detect infrared-specific band signals of thermal radiation of objects, converts the signals into images and graphics that can be distinguished by human vision and can further calculate the temperature value. Infrared thermal imaging technology enables humans to transcend visual barriers so that people can "see" the temperature distribution on the surface of objects.

Most developers of machine vision and image processing systems already use cameras operating in the visible wavelength range for quality control, process control, or those applications that need to distinguish objects. Traditional visible light imaging uses broadband white light illumination, which allows the camera to see all visible colors. For more efficient viewing of certain colors, developers can also select specific wavelengths of illumination light, such as red, blue, or green.

1. High recognition degree: Short-wave infrared SWIR imaging is mainly based on the principle of target reflected light imaging. Its imaging features are similar to visible light grayscale images, with high imaging contrast and clear target details. In terms of target recognition, SWIR imaging is an important supplement to thermal imaging technology;

2. All-weather adaptation: Short-wave infrared SWIR imaging is less affected by atmospheric scattering, has a strong ability to penetrate fog, haze, and smoke, and has a long effective detection distance. The adaptability to climatic conditions and battlefield environments is significantly better than that of visible light imaging;

3. Low-light night vision: Under the night vision condition of atmospheric glow, the photon irradiance is mainly distributed in the SWIR band range of 1.0-1.8μm, makes the SWIR night vision imaging have a significant congenital advantage over visible light night vision imaging;

4. Stealth active imaging: In the 0.9-1.7μm band, the military laser light source technology is mature (1.06μm, 1.55μm, 1.06μm, 1.55μm, which makes the short-wave infrared InGaAs focal plane imaging have a significant comparative advantage in stealth active imaging applications;

5. Simple optical configuration: Optically, the glass light window has a high transmittance in the SWIR band, which gives short-wave infrared imaging an important technical advantage, which allows the SWIR camera to be assembled in a protective window to achieve high Sensitive imaging, which provides great flexibility when applied to a specific platform or situation.
