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 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.

• Q4: 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 NETD? 

  • A: 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.

• Q7: What is SWaP3? 

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

• Q8: What is DRI? 

  • A: 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.

• Q9: 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.

• Q10: 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.

• Q19: Does using a thermal imaging camera require preheating? 

  • A: All thermal imaging cameras require adequate warm-up time to obtain accurate temperature measurements and optimal image quality, and warm-up time often varies with model and environmental conditions.

• Q20: What is the accuracy range of a thermal imaging camera? 

  • A: In accordance with national standards, the accuracy of infrared thermal imaging cameras is ±2% of the reading or ±2°C, whichever is greater.

• Q21: What is FOM? 

  • A: FOM value, calculated as clarity*signal-to-noise ratio, is used to evaluate the overall performance of night vision devices. For this parameter, 1000 is the minimum acceptable standard, 1600 is good to use, and 2100+ is pretty great.

• Q22: What is FOV? 

  • A: FOV is the field of view, also known as the field of view. With the lens of the optical instrument as the vertex, the angle formed by the two edges of the maximum range through which the object image of the measured target can pass through the lens is called the field of view angle. The size of the field of view determines the field of view of the optical instrument. The larger the field of view, the larger the field of view and the smaller the optical magnification.

• Q23: What is laser ranging? 

  • A: The distance to the target is calculated by emitting a laser beam and measuring the time it takes from emission to reception. A laser rangefinder usually includes an emitter, a detector and a sensor, where the emitter emits a laser beam to the target, the detector receives the laser beam reflected from the target and calculates the distance by measuring the flight time of the laser beam.

• Q24: Why can infrared night vision goggles be used during the day? 

  • A: Infrared night vision devices have two modes: infrared and visible light, so they can be used in all scenarios day and night. However, low-light night vision devices cannot be used during the day. Low-light night vision devices are image-intensifying tube night vision devices, which are afraid of strong light during the day.

• Q25: How to distinguish between second-generation and third-generation image intensifiers? 

  • A:

    The third generation image intensifier uses gallium arsenide (GaAs) photocathode, which significantly improves the utilization of night starlight spectrum, has higher sensitivity and quantum efficiency, and can better convert light signals into electronic signal, resulting in clearer images.

    Second generation image intensifier: usually uses a multi-alkali photocathode, such as S25 material, and its spectral response range and sensitivity are relatively limited.

• Q26: What is the core of thermal imaging night vision goggles? 

  • A:

    The core component of thermal imaging night vision goggles is the infrared detector, which works based on the detection principle of infrared radiation. All objects will radiate infrared rays as long as the temperature is higher than absolute zero (-273.15℃), and the infrared detector can sense these infrared rays. It converts the received infrared radiation into electrical signals to provide a basis for subsequent imaging.
