Main parameters of infrared thermal imaging camera

As a typical high-end application equipment, with the continuous improvement of manufacturing technology, the performance of infrared thermal imaging cameras has been significantly improved today. Here we will systematically introduce the main parameters of infrared thermal imaging cameras.

1. Frame rate

The frame rate refers to the number of images that the thermal imaging camera can capture, process, and display within 1 second. The faster the sensor response and the higher the internal circuit processing speed, the higher the achievable frame rate. Thermal imaging cameras with high frame rates are suitable for capturing the temperature field distribution of high-speed objects. More suitable for scientific research and military research.

2. Pixel array and pixel spacing

Current infrared thermal imaging camera detectors are uncooled focal plane detectors. During the production process, sensor units arranged in an array are processed on vanadium oxide or polysilicon materials, with a certain spacing between each unit.

3. Temperature measurement accuracy

Accuracy refers to the percentage of the maximum temperature measurement error of the infrared thermal imaging camera to the instrument range when the infrared thermal imaging camera is calibrated to the environment, temperature, humidity, distance, and emissivity.

4. Display mode

According to professionals, this usually refers to whether the display on the thermal imager screen is black and white or pseudo-color.

5. Temperature measurement range

For thermal imaging cameras, during normal operation, there will always be a certain temperature measurement range, which refers to the range of the lowest and highest temperature values of the measured temperature.

6. Temperature resolution

Temperature resolution specifically refers to an important parameter index for measuring infrared thermal imaging cameras. Temperature resolution refers to the sensitivity of the detector to temperature changes of the measured object. The smaller the temperature resolution, the better. The measurement and determination of temperature resolution are completed under specific conditions.

7. Scanning format and maximum working time

These two are often parameters that people tend to ignore. The former refers to my country's standard TV system, PAL system. The latter refers to the continuous working time allowed by the thermal imaging camera.
