Infrared sensors are electronic equipment designed to sense infrared radiation given off by objects through heat and transform it into quantifiable electric energy. There are three different spectrum bands for the industry - the short-wave infrared with wavelengths ranging from 0.9 to 2.5 micrometers, the mid-wave infrared that spans from 3 to 5 micrometers, and the long-wave infrared from 8 to 14 micrometers, each with its unique features. Operation techniques classify the device into either active infrared sensors that generate IR radiation and reflect it or passive ones that measure ambient heat. Thermal infrared sensors and quantum infrared sensors are examples of the infrared sensors available on the market. They can be categorized based on the detection method into uncooled sensors that provide affordable solutions and cooled sensors that have high sensitivity. The end-users for infrared sensors include healthcare, aerospace & defense, automotive, commercial, manufacturing, and oil & gas sectors.
The conflict within the market is located on the interface of defence and commercial. While defence quality cooled infrared sensors based on state-of-the-art focal plane array technologies provide performance specifications demanded by commercial application in autonomous driving cars and healthcare diagnostics, high prices and export control limitations via ITAR make this technology less accessible and thus contribute to maintaining distinct paths of technological development. The challenge is driving increased investments into developing commercial grade detectors that continuously reduce the performance gap while providing economic benefits that allow scaling up into the consumer market of automotive and smart buildings markets. An example here would be Teledyne FLIR which positions itself both as the largest producer of ITAR-free infrared modules and defense sensor technologies.
In January 2024, Teledyne FLIR launched an upgraded K-Series thermal imaging camera for firefighting and search and rescue applications, offering improved image clarity in low-contrast conditions to enhance operator safety and field performance.

Global defence budgets are growing because countries need to acquire military systems which depend on advanced infrared technology for their surveillance and reconnaissance and targeting operations. Smart building automation programmes which require occupancy detection and HVAC optimisation and perimeter security systems are now using passive infrared sensors at all commercial properties and healthcare facilities and public infrastructure sites. The two market trends are creating ongoing procurement needs which will last for several years to infrared sensor manufacturers who supply both defence and commercial market applications.
High cooled sensor costs and complex calibration requirements continue to restrain infrared sensor expansion.
Cooled infrared sensors delivering the highest sensitivity and resolution carry production costs that limit their addressable market to high-value defence, aerospace, and specialist scientific applications. The cryogenic cooling mechanisms required add size, weight, power consumption, and maintenance complexity that commercial applications cannot absorb at competitive price points. The calibration needs for temperature range testing create extra qualification challenges which extend the approval process time for automotive medical and industrial sectors that need complete performance testing before their products can enter commercial markets.
Automotive ADAS integration and precision agriculture monitoring offer strong infrared sensor market opportunities.
There is a fast-growing procurement level for infrared sensors used in automotive ADAS, as applications for pedestrian detection, enhanced night vision, and crash avoidance are all reliant on high-quality thermal imaging that cameras simply cannot deliver in low-light situations. Less well-known but still commercially viable is the area of precision agriculture, where infrared sensors are being applied to measure crop conditions, moisture in the soil, and even the vital signs of livestock - maximizing output that could not be obtained in similar fashion five years ago.
Supply chain constraints and export controls on defence-grade infrared sensors challenge market participants.
ITAR export control laws limit the global sales of high-efficiency cooled infrared sensors and the technology behind their focal plane array design, resulting in the segmentation of supply chains and preventing the entry of U.S. companies into the global market, forcing customer nations that are allies to the U.S. to find alternate domestic sources for their needs. Procurement difficulties arise due to limitations in the semiconductor supply chain for detectors made of indium antimonide and mercury cadmium telluride. Companies that do not fall under the ITAR laws, such as French company Lynred and domestic Chinese manufacturers, are benefiting from the current situation.
Uncooled detector advances, AI integration, and miniaturisation reshape the infrared sensor technology frontier.
The uncooled microbolometer technology is currently making strides towards further miniaturization down to 12 micrometres, resulting in higher resolutions at smaller sizes and lower costs, allowing the long-wave infrared (LWIR) sensors to be utilized across multiple applications such as automotive, smart buildings, and health monitors. Artificial intelligence (AI) integrated imaging systems are already being embedded in the sensors themselves, providing on-the-spot image analysis for identifying objects and anomalies, as well as offering autonomous decision-making capabilities without relying on any other computing system.
