FAQs

• Q1: What is infrared thermal imaging? 

  • A: Infrared thermal imaging is a method of using infrared radiation and thermal energy to gather information about objects, in order to formulate images of them, or get temperature information of the objects, even in low visibility environments.

• Q2: What is thermography? 

  • A: Thermography is a non-invasive diagnostic method, based on object surface temperature detection. The infrared (IR) radiation emitted from an object is recorded and visualized in the form of a temperature distribution map. The infrared thermal image can be used to determine structural defects, electrical faults, mechanical faults, physiological changes in people & animals, and much more.

• Q3: What is the advantage of infrared thermal imaging? 

  • See through total darkness
  • Identification under camouflage
  • Long range detection
  • Heat distribution detection
  • Non-contact temperature measurement
  • Occupation awareness

• Q4: What is infrared detector/thermal imaging sensor? 

  • A: Infrared waves cannot be seen with the human eye. Infrared detector/thermal imaging sensor is an optical-electrical device to react to infrared radiation and thermal energy and convert it into electrical signal and then output visible thermal images.

• Q5: What is the difference between uncooled and cooled IR detectors? 

  • A: There are currently two types of infrared thermal imaging sensors on the market, cooled and uncooled.Uncooled IR detectors operate at ambient temperature. It is based on semi-conductor industry and thus usually can be fabricated in big volume with small size and low cost. Uncooled IR detectors are widely used in portable/handheld/mobile devices.Cooled IR detectors are packaged in a unit that keeps them at an extremely low temperature which shall be supported by a cyrocooler. They are much bigger, more expensive and less reliable than uncooled sensors, mainly due to the complex cooling systems they require. However, the cooled systems are incredibly sensitive and usually work with long focal length optics to achive long range mission.knowing the conditions in which the IR detectors will be used is crucial to making the right choice.

• Q6: What is thermal imaging module?

• Q7: What is NETD? 

  • NETD refers to "Noise Equivalent Temperature Difference". It is a measure of how well a thermal imaging detector is able to distinguish between very small differences in thermal radiation in the image. NETD is typically being expressed in milli-Kelvin (mK). Usually the lower the NETD figure is, the higher the thermal sensitivity indicates.

• Q8: What is SWaP3? 

  • SWaP3 refers to size, weight, power, performance and price. It indicates the technology trend of infrared industry.

• Q9: What is DRI? 

  • DRI usually refers detection, recognition and identification distance of a thermal imaging system. It is a crucial parameter to judge the performance of the thermal imaging system.

• Q10: What is WLP? What's the advantage of WLP? 

  • A: WLP refers to wafer level package. Together with metal package, ceramic package, they are the 3 main package formats of uncooled infrared detectors. Wafer level packaging (WLP) is the process of completing high vacuum packaging directly on the entire MEMS wafer, then scribing and cutting to make a single infrared detector. WLP IR detectors are just designed to meet the miniaturization and low cost requirement in the application of infrared technology to consumer electronics market. Global Sensor Technology, with volume fabrication capability, is now offering a variety of WLP infrared module solutions to boost more new applications of emerging markets.

• Q11: How does infrared thermal imaging contribute to COVID-19? 

  • A: Infrared Fever Sensing System helps to prevent the spread of the epidemic by detecting individuals with elevated body temperature in a high-traffic places such as airport, train stations, office building, supermarket, schools, factories etc.

• Q12: What are the key considerations on an infrared detector/module for your application? 

  • The detector resolution
  • The pixel size
  • The NETD
  • The image quality
  • The lens options
  • The power consumption
  • The size and weight
  • The mechanical & electrical interface
  • The budget
