ITH1212IP： ITH1212IP Infrared thermal imaging core is small in size, low in power consumption, and strong in performance
The advantages exhibited by uncooled thermal imaging cameras present a dilemma: when to use cooled thermal imaging cameras for R&D/scientific applications? The answer is: that it depends on the application requirements.
If you want to spot small temperature differences and need image quality, shoot fast moving or hot objects; if you need to see thermal changes clearly, or measure the temperature of very small objects; if you want to see how objects in very well-defined parts of the electromagnetic spectrum; or if you want to synchronize the thermal imaging camera with other temperature measurement equipment, a cooled thermal imaging camera is the right instrument for you.
Cooled thermal imaging cameras can image faster than uncooled thermal imaging cameras. High-speed thermal imaging has exposure times down to microseconds, stops the apparent motion of dynamic scenes, and captures frame rates of more than 62,000 frames per second. Applications include thermal and dynamic analysis of jet engine turbine blades, automotive tire or airbag inspection, supersonic projectiles, and explosions.
Cooled thermal imaging cameras are extremely responsive and take full advantage of the global shutter. This means they can read out all the pixels simultaneously, rather than line by line like uncooled cameras, allowing cooled cameras to capture sharp images and measure the temperature of moving objects.
2. Spatial resolution
The thermal images below compare the close-up magnification achievable with cooled and uncooled thermal imaging systems. The infrared image on the left was taken with a combined setup with a 4x near-focus lens and a cooled thermal imaging camera with a pixel pitch of 13μm, with a spot size of 3.5μm. The infrared image on the right was taken with a combined setup with a 1x near-focus lens and an uncooled thermal imager with a pixel pitch of 25μm, with a spot size of 25μm.
