Infrared thermal imaging technology

Infrared thermal imaging technology is a technique that uses the infrared radiation emitted by objects to generate thermal images. Here is an introduction to it:

In nature, as long as an object's temperature is above absolute zero, it will emit infrared radiation. Infrared thermal imaging technology captures the infrared radiation emitted by objects through an infrared lens. The infrared detector then converts it into an electrical signal. The signal processing circuit amplifies, processes, and transmits the electrical signal. Finally, the image processing circuit uses image algorithms to process and optimize the image effect, converting the electrical signal into a visible thermal image.

Infrared Detector: This is the core component, which can be divided into cooled and uncooled types. Cooled detectors have high sensitivity and resolution, often used in high-end equipment; uncooled detectors are small in size and low in power consumption, widely used in the civilian market.

Infrared Lens: Responsible for collecting the infrared radiation of objects and focusing it on the infrared detector. Specially designed lenses can meet the needs of different application scenarios.

Signal Processing Circuit and Image Processing Circuit: The signal processing circuit is responsible for driving the detector and collecting and digitizing the output signal; the image processing circuit enhances the image details of the signal to output an easily analyzable thermal image.

All-weather operation: It can clearly image in completely dark nights and under adverse weather conditions such as rain, snow, fog, and haze.

Strong penetration: It can penetrate obstacles such as smoke and dust. For example, in a fire scene, it can penetrate thick smoke to find the fire source and trapped people.

Good concealment: As a passive non-contact detection technology, it is not easily discovered, suitable for covert surveillance.

High sensitivity and high accuracy: It can detect tiny temperature changes, which can be used in industrial equipment fault diagnosis and early medical disease detection, etc.

Military field: Equipped on aircraft, ships, and tanks as an all-weather forward-looking system for night surveillance, reconnaissance, and aiming, etc.

Security field: Surveillance cameras use infrared thermal imaging technology to achieve 24-hour all-weather monitoring and promptly discover potential safety hazards.

Industrial field: Used for fault diagnosis and preventive maintenance of electrical equipment, mechanical parts, etc., it can detect equipment overheating, leakage, and other issues.

Medical field: It can detect the temperature distribution on the human body surface, assisting in the diagnosis of diseases such as inflammation, tumors, and tissue damage. It can also be used for body temperature detection and disease screening, etc.

Firefighting field: Helps firefighters quickly locate the fire source and trapped people, improving rescue efficiency.

Automotive field: As a night vision assist function, it provides information outside the headlight range for the driver. It can also be integrated into intelligent driving systems to assist in vehicle recognition and warning.
