Home/Industry Trends/Application Analysis
As low-altitude economy policies advance and automotive infrared night vision becomes widespread, infrared thermal imaging applications are rapidly expanding across sectors. However, as applications become more critical—in vehicles, aircraft, and medical settings—measurement accuracy becomes the decisive factor for compliance and quality. This is underpinned by capabilities in NETD, MRTD, and temperature calibration.
Policy Support: The low-altitude economy has been written into China's Government Work Report for two consecutive years (2024, 2025) and has been incorporated into the strategic emerging industry direction. The National Development and Reform Commission established a "Low-Altitude Economy Development Bureau" in December 2024 to coordinate airspace, safety, and standards. This has unlocked demand for infrared payloads on low-altitude vehicles like UAVs and eVTOLs.
Application End: Automotive far-infrared night vision is now appearing on multiple passenger vehicles, used for identifying pedestrians and animals in darkness, rain, and fog for early warning. Applications in power line inspection, security, medical care, and industrial temperature measurement are also continuously expanding. The key driver for faster penetration is cost reduction (a significant drop in prices of uncooled detectors). (Vehicle models, penetration rates, and market size data cited from media reports or institutional projections may vary; primary sources should be referenced.)
The more critical the application, the more stringent the testing requirements:
In other words, alongside the application surge, the testing and calibration of every infrared device before it leaves the factory has become the unified foundation for quality and compliance.
Whether for vehicles, aircraft, or hospitals, whether infrared equipment "sees accurately" ultimately comes down to a set of measurable, traceable metrics: NETD/MRTD/MTF determine imaging quality, while blackbody calibration and metrological traceability determine the credibility of temperature measurements. As applications diversify, this metrology system becomes indispensable.
Low-altitude vehicles like UAVs and eVTOLs require infrared payloads for detection, inspection, and positioning during night operations and in complex weather. Coupled with policy support in China (e.g., inclusion in successive Government Work Reports and the establishment of a dedicated development bureau), this demand is set to grow.
Automotive night vision is used in active safety scenarios like pedestrian recognition in darkness or fog, directly relating to systems like AEB and compliance with safety standards. This necessitates high-performance testing and stable results for key imaging metrics like NETD and MRTD.
Accuracy depends on calibrated, traceable blackbody references and standardized testing procedures. Factory and periodic calibration are prerequisites for ensuring reliable on-site readings.
Measurement values are traced to national standards through calibration against reference blackbodies. Errors are kept within specified limits by setting emissivity according to specifications during use and performing periodic recalibration.
From components to complete systems, IES provides Thermal Imager Comprehensive Test Systems and Portable Blackbodies, supporting NETD/MRTD/MTF testing and temperature calibration in both lab and field environments—providing foundational support for measurement accuracy in infrared applications across vehicles, aircraft, and healthcare.
