How to Ensure Infrared Thermal Imaging Device Quality?

Infrared thermal imagers detect infrared radiation emitted by objects and generate thermal distribution maps. They enable non-contact measurement in high-temperature, hazardous, or hard-to-reach environments.

Key Features:

· Real-time thermal imaging for rapid anomaly detection
· High temperature accuracy and spatial resolution
· Non-invasive and safe testing
· Widely used in industry, healthcare, construction, security, automotive night vision, and firefighting rescue

Expanding Applications of Thermal Imaging

Originally developed for defense and night-vision operations, infrared thermal imaging is now rapidly penetrating civil markets such as autonomous driving, medical diagnostics, power inspection, and security surveillance. As adoption accelerates, manufacturers face increasingly strict requirements for image quality, compliance, and reliability.

Yet in R&D and mass production, manufacturers often encounter serious challenges: low resolution, poor temperature sensitivity, unstable images. These issues not only reduce reliability in real-world scenarios but can also result in failure to pass certification standards like GB/T 43249, leading to lost market opportunities.

To overcome these bottlenecks, thermal imaging manufacturers must establish a full-process image quality testing and calibration system that can detect hidden defects early and ensure products meet international standards.

Core Quality Challenges in Thermal Imaging Production

Image quality directly impacts downstream application safety and effectiveness. Even small deviations can cause critical risks. Below are the main pain points every manufacturer must address:

Pain Point	Problem	Application Example
Insufficient Resolution	Blurred details, failed object recognition	Power inspection, autonomous driving
Low Temperature Sensitivity (NETD)	Weak thermal targets undetectable	Early medical inflammation, chip overheating
Non-uniform Image	Stripes/spots distort detection	False alarms in surveillance
Slow Dynamic Response	Motion blur, delayed alerts	Automotive night vision, assembly line inspection
Temperature Drift & Stability	Biased measurement under varying environments	Vehicle-mounted or outdoor power inspection
Defective Pixels & Narrow FOV	Image integrity loss, blind spots	Dead pixels, limited coverage

Why Full-Parameter Testing & Calibration is Essential

From R&D verification to production quality control, each core parameter must be validated to ensure both compliance and safety.

Relevant standards include:

· GB/T 43249-2023 Passive Infrared Detection System for Vehicles

· GA/T 1708-2020 Security Infrared Thermal Imagers

· GB/T 19870-2018 Industrial Infrared Cameras
