What is thermal detector of thermal imaging

Thermal detector is the core of a thermal imaging camera.

It is the use of infrared radiation and physical interaction of the physical effects of infrared radiation detection of the sensor, in most cases is the use of this interaction presented by the electrical effect. Such detectors can be divided into two types of photon detectors and heat-sensitive detectors.

The thermal detector utilizes the radiant heat effect, which makes the temperature to rise after the detection element received the radiant energy, and then to make the temperature dependent performance of the detector change. Detection of a change in performance, that can detect radiation.

In most cases radiation, it is detected by thermoelectric changes. When the element receives radiation and causing a physical change in the non-electrical quantity, the corresponding change in the charge can be measured by a suitable transformation.Infrared sensors have been playing an important role in the modern production practice. With the improvement of detection equipment and other parts, the infrared sensor can have more performance and better sensitivity.

Nature of all temperatures in absolute zero (-273 ℃) above objects will be issued by infrared radiation, infrared image sensor will detect the infrared radiation into the human eye visible image information.Infrared imaging technology covers infrared optics, materials science, electronics, mechanical engineering technology, integrated circuit technology, image processing algorithms and many other technologies, infrared imaging device is the core of the infrared focal plane detector.

Uncooled infrared detectors use infrared radiation thermal effects, infrared absorption of infrared radiation energy into heat energy, causing the temperature rise of sensitive components. A physical parameter of the sensing element changes with it, and then converts it into an electrical signal or a visible light signal through a designed conversion mechanism to realize the detection of the object.

IR laser illumination camera system- see clearly at night

How can a person see clearly at night for the around? With the rapid development of IR technology, IR laser illumination camera system has been proved to good using for security video surveillance.

Laser light belongs to Near Infrared light.

IR Laser illumination light adopts semiconductor laser as light emitting device. The output is light, thus can be used as light source. With reason of directionality features and narrow width of beam, the laser infrared can emit in long distance with intensity light, therefore it’s suitable for long range distance illumination. Long range distance illumination is the most important features for IR laser light.

CCD and CMOS B/W camera could capture the IR laser and display the clearly imaging at complete darkness conditions.

Advantages of IR laser camera system

Long range zoom surveillance.

The laser illumination light of a laser camera could be flexible adjustment, the FOV, the aperture. Large field of view to obtain long range targets, telephoto zoom to obtain the details of targets.  People’s eye can’t see the IR laser light, so the IR laser camera is very covert to prevent thieves.Easy to be integrated into any surveillance system. Only using few IR laser cameras that could cover a large field. IR laser camera is a cost-effective product.

The working life of IR laser camera is very long, and also high efficiency. More than 10000 hours working time that will save the power and energy.

IR laser camera is widely used for variety of applications. Such as Oilfield monitoring, navigation, fishery, aquaculture, railway&freeway security, seaport&airport security, mariculture security, city security and forest fire prevention.
