The high-speed infrared thermal imager is a graph of the energy distribution
of infrared radiation reflected by an infrared detector and an optical imaging
objective lens and reflected on the photosensitive element of the infrared
detector to obtain an infrared thermal image consistent with the infrared
detector. The heat distribution on the surface of the object. Commonly used
high-speed infrared thermal imaging equipment converts the invisible infrared
energy generated by an object into a visible thermal image. The different colors
above the thermal image indicate the temperature of the measured object. So, how
to use a high-speed thermal imaging camera for thermal imaging? Let's take a
look with the staff below.
Correct use of high-speed thermal imaging cameras:
1. Key search: Generally, a high-speed infrared thermal imaging camera is used to perform a comprehensive scan of the corresponding parts, and find the abnormal heating parts, and then conduct key inspections on the abnormal temperature parts to accurately measure the temperature. Correspond the temperature of the abnormal point with the historical operating temperature. When the real temperature changes greatly, record and analyze.
2. Adjust the focal length: After the image is saved, the image curve can be adjusted, but the focal length cannot be changed after the image is saved, nor can other messy heat reflections be eliminated.
3. Temperature measurement range: In order to ensure the correct temperature reading, the correct temperature range must be set. When observing the target, by appropriately adjusting the temperature measurement interval, a good imaging effect can be obtained. At the same time, the quality and measurement accuracy of the temperature curve will also be affected.
4. Distance measurement: When measuring the target temperature, in order to measure the temperature, the range of the distance must be known. For uncooled micro-thermal focal plane detectors, more than 9 pixels are required to obtain the target image from the thermal imaging optical system. Since the measured temperature is measured as the temperature of the target object and its surrounding environment, it cannot accurately reflect the temperature of the target object, and therefore cannot accurately reflect the temperature of the target object.
5. First, I will introduce the purpose of high-speed infrared thermal imaging camera. The human eye cannot directly see the temperature distribution on the surface, but can only see the temperature map. All objects with a temperature above zero (-273°C) will continue to emit thermal infrared rays.
