Application of Short-wave Infrared Thermal Imager in Marine Aquaculture

An infrared lens means that the transmittance of the long-wave band (700-950nm) of the infrared spectrum is very high, and the lens has a control device to control the passage of long-wave infrared.

Infrared lenses are used in conjunction with high-performance day and night fog cameras. SWIR cameras capture very clear, high-contrast black-and-white images even in visible light (color images) environments such as fog, dust, smoke, light rain, etc. Compared with ordinary lenses, the long-distance observation effect is increased by 3-5 times.

Using the principle that near-infrared light can diffract tiny particles, near-infrared color filters, coating technology, and electronic image enhancement technology are used to penetrate fog on foggy days. The monitoring distance is more than 1.5 times that of the visibility, and there is no longer a blind spot for long-distance all-weather security monitoring.

The marine aquaculture infrared camera monitoring is mainly aimed at monitoring the natural environment, typhoon intrusion, theft, and invasion of the fishing port area and the marine aquaculture functional area.

In recent years, my country's marine aquaculture has strengthened the management of fishery law enforcement, theft prevention management in aquaculture areas, and natural disaster operations in aquaculture areas. It has begun to introduce video surveillance systems, replacing traditional manual methods with high-tech remote surveillance systems and large zoom infrared lenses. With the advantages of high definition, telephoto, and fog penetration, it is widely used in fishery and aquaculture monitoring in my country.

Due to the special use environment and target, most of the current infrared lenses are divided into DC drive and video drive, the aperture can be changed, and there are few manual adjustments.

Due to the physical characteristics of optical technology, it is difficult to make a major breakthrough in the focal length and mirror surface size of infrared lenses in recent years.

Due to the large monitoring range and long distance, a telephoto lens is generally used, and the day and night mode can meet the monitoring needs of day and night.

Smoky days are like a brick wall that effectively blocks the light, and it's really hard to take pictures without a bit of wall-climbing skills. Therefore, short-wave infrared cameras came into being. Its core camera defogging technology can remove blurred images caused by fog, moisture, dust, etc., and improve image quality.

Through the combination of optics and algorithms, the short-wave infrared camera automatically adjusts according to the image impurity concentration, compensates for the image chromaticity, and obtains a clear image that is closer to the real scene.

SWIR cameras are used in conjunction with high-performance day and night fog cameras. Even in the environment of visible light (color image) such as fog, dust, smoke, light rain, etc., it can capture very clear, high-contrast black and white images, which enhances the long-term observation effect by 3-5 times compared with ordinary lenses.

Short-wave infrared thermal imaging cameras are derived from the monitoring needs of long-distance and complex environments. Fog is made up of tiny particles floating in the air. The more particles per unit volume, the denser the fog.

Visible light has shorter wavelengths and cannot penetrate mist, which is why visibility is poor on foggy mornings. The wavelength of near-infrared light is longer so that infrared light diffracts small particles and achieves the purpose of passing through the fog.

In fog mode, the filter filters out visible light, leaving only infrared light. With coating anti-reflection technology, the infrared lens can achieve long-distance all-weather monitoring even in extremely low visibility conditions and can be maintained in normal mode and fog mode.
