Thermal imaging technology is a technology that converts thermal signals into visual images by detecting infrared thermal radiation emitted by objects. It has a wide range of important application scenarios in optical instruments. The following is a classification explanation from different fields:

I. Industry and manufacturing

1. Equipment fault detection and maintenance

Application scenarios: power system (transformer, cable connector overheating detection), machinery manufacturing industry (bearing wear, motor overload heating monitoring), chemical pipeline (temperature anomaly investigation caused by leakage or blockage).

Instrument type: handheld thermal imager, online thermal imaging monitoring system.

Advantage: non-contact detection, which can quickly locate hidden dangers without interrupting production and avoid downtime losses.

2. Production process optimization

Application scenarios: metal processing (welding temperature field monitoring, heat treatment uniformity analysis), semiconductor manufacturing (chip thermal distribution detection, packaging process defect location), 3D printing (layer-by-layer temperature control to optimize molding quality).

Instrument type: high-precision thermal imaging camera, infrared thermal imager integrated into the production line detection system.

2. Security and monitoring

Application scenarios: Searching for trapped people in disasters such as earthquakes and fires (penetrating smoke to detect human heat sources), searching and rescuing lost people in the wild (locating heat signals at night or in complex terrain).

Instrument type: portable thermal imager, helicopter/drone-mounted thermal imaging search and rescue system.

2. Wildlife Protection

Application scenarios: Night animal population monitoring (avoiding visible light from interfering with animal behavior), illegal poaching prevention (thermal imaging cameras monitor protected areas in real time).

Instrument type: high-precision thermal imager, infrared radiation calibration equipment.

2. Military reconnaissance and night vision

Application scenarios: single-soldier combat (thermal imaging night vision device to identify enemy personnel and equipment), armored vehicle fire control system (thermal imaging sight to achieve all-weather combat).

Technical features: Military-grade thermal imagers usually have higher sensitivity, anti-interference ability and concealment.

VII. Scientific research and laboratory scenarios

1. Material science research

Application scenarios: new batteries (heat diffusion monitoring during charging and discharging), nanomaterials (heat conductivity characteristics analysis), phase change materials (temperature field recording during state change).

Core advantages of thermal imaging technology

Non-contact: no need to directly contact the target, suitable for high temperature, high pressure, and dangerous environments.

All-weather capability: not limited by visible light, can work in darkness, haze, and smoke.

Real-time and visualization: quickly generate thermal images, intuitively display temperature distribution, and facilitate data analysis.
