Who Are the Leading Manufacturers of the Best Infrared Thermal Imaging Cameras?

16/8/2016

Thermal imaging cameras came into being sometime during the 1950s for military application. Also known as thermographic cameras or infrared imagers, these cameras used to be bulky devices at one time. This was because the technology of the time required liquid nitrogen for cooling the detector system. The classified nature of the technology and the exorbitant rates meant that these cameras hardly available for use in various civil and commercial applications. This changed in the following decade. The development of uncooled detectors and advances in infrared viewing technology made these cameras more affordable. Today, numerous manufacturers provide a diverse range of thermal cameras across the world. Some of the major manufacturers comprise:

Jenoptik: Founded in 1991 in Germany, Jenoptik has a presence in around 80 countries across the globe. An integrated photonics group, it operates in domains such as lasers & material processing, optical systems, industrial metrology, traffic solutions and defence & civil systems. Its clients include businesses in the semiconductor equipment manufacturing, automotive supplying and medical technology industries. The IR-TCM 640 High Resolution IR Module and the VarioCAM High Resolution thermography cameras are among their most popular thermal IP cameras.
Nippon Avionics: A Japanese company with over 50 years of operational experience, Nippon Avionics specialises in developing and designing data processing systems.

What Are Some of the Most Significant Aspects to be Aware of About Thermal IP Cameras?

Thermal imaging cameras capture objects based on the amount of infrared heat or energy they emit. Thereafter, they present these images in different shades of grey, highlighting various temperature ranges. Unlike regular cameras, thermal imaging cameras function by using infrared light. In contrast, regular cameras operate on the basis of reflected light. This difference enables thermal imaging cameras to provide images even in low or poor visibility conditions.

However, it’s essential to be aware of certain facts when you’re thinking of using them to boost your security levels. Thermal imaging cameras:

Do Not Measure Temperature Directly: Thermal cameras do not measure temperature levels of objects directly. Instead, they provide estimates based on:
oThe infrared radiation of the object
oThe emissivity of the object and,
oVarious other factors
Provide Surface Temperatures Only: Thermal cameras cannot see into the object. As such, they can only provide details of the surface temperature of the object. Similarly, in visible light, window glazing appears transparent. But, when viewed in infrared light, window glazing would typically be opaque. So, if you happen to take an infrared image through a window, you will not get an image of objects lying on the other side of the window. Instead, all that you will get will be the surface temperature of the window glazing.
Must Provide the Temperature Scales While Viewing the Object: As mentioned earlier, thermal cameras produce images in various shades of grey. These different shades denote specific ranges of temperature. Now, the average user will not be able to understand what these shades represent. Therefore, it is imperative that these cameras provide temperature scales as well. The users would be able to use these scales for mapping each shade to its respective temperature range.
Reflect Infrared Radiation as Well as Visible Radiation: Shiny surfaces reflect infrared rays quite well. As a result, the reflections in the thermal image will reflect the temperature of the object being reflected and not the temperature of the shiny surface itself

How Do Thermal Image Cameras Work?

3/8/2016

To understand how thermal imaging cameras work, it is essential to understand how the human eye works. The human eye operates by virtue of seeing all the objects illuminated by the sun or any other source of light. The contrast between objects illuminated by the sources of light enables the human eye to distinguish between two objects. In contrast, thermal imaging cameras work by seeing the heat energy that the objects in the frame emit. As mentioned earlier, all objects (whether living or not) have heat energy. Thermal imaging cameras detect this energy and provide an image accordingly. The ability to detect infrared energy makes these cameras highly accurate. This is so even in conditions of complete darkness.

Unlike digital cameras that work by using reflected light, thermal cameras work by seeing heat. As such, the images these cameras produce will be very different from those produced by regular cameras. It is evident that each object will emit varying levels of infrared energy or heat. Thus, thermal imaging cameras have the ability to convert the temperature of objects into shades of grey. These shades will typically be lighter or darker than the background. For instance, the picture of a person will be lighter than the background on a cold day. This is because the person is hotter than the background. Similarly, on a hot day, a person will appear to be darker than the background. This is because the person is cooler than the background
