Infrared (IR) sensors are the sensors that respond to infrared radiation by displayingperceptible and measurable changes in their physical and/or electrical properties.

Infrared rays were discovered approximately 200 years ago. Methodologies to senseinfrared rays are nearly 100 years old. Surprisingly, the industry associated with suchwidely known and understood technology is largely restricted to less than 10 principalapplications. The most compelling factor keeping the technology restricted is itsassociation with defense-related operations. This association has enforced a strict andeffective embargo on the commercialization of infrared detectors. In light of such aformidable challenge, it is notable that the current infrared ecosystem spans hundredsof companies of varying pedigrees spread all over the world. The reason forwidespread acceptance of infrared sensing technologies is their simplicity. Basically,infrared sensors are either thermal detectors or photon analyzers. Thermal detectionshould rank among the most widely understood and practiced transduction

mechanisms. It has low entry barriers and enjoys widespread adoption. Thermaldetectors are, however, hampered by low sensitivity and poor temperature response.The alternative, which comes in the form of quantum detectors, is inherently expensiveand requires elaborate cooling mechanisms for seamless operations.

This report is an attempt to capture the present-day health and future prospects of theinfrared sensor industry, which must walk a tightrope between the ever-growingdemand for quicker and accurate readings on one hand and the availability of limitedinnovative bandwidth on the other.

This report uses the term sensors and detectors interchangeably.


Infrared detectors are among the most understood technology components, but thereis little appreciation regarding their contribution in quantitative terms to the productsthat embed them. This report sheds light on the value addition imparted by infraredsensors and devices in qualitative and quantitative terms. Additionally, by combiningimage sensors along with others parameter-sensing technologies, this report is in aposition to provide a unique perspective on the relative sizes of the respective markets.It also provides a detailed breakdown of individual applications by theparameter-sensing technologies involved, as well as by region. The report alsoprovides a granular breakdown of stakeholder categories associated with infraredsensors and the devices that embed them.

The report examines the infrared sensor/detector market under key parameters:

  • Parameter-sensing technologies
  • Application
  • Regional dynamics
