Field Calibration of Your imaging system
El tema de calibración y exactitud de las mediciones de las cámaras infrarrojas podría muchas veces desatar diferentes opiniones. Aun los usuarios de la termografía más capacitados podrían conocer las limitaciones de las mediciones de temperatura radiométrica, y también podrían haber aprendido técnicas para mejorar la...

Field Calibration of Your imaging system
The topic of calibration and accuracy of measurement in infrared imaging systems is one that tends to stir debate when it inevitably comes up. Most trained thermographers understand the limitations of radiometric temperature measurement and have learned techniques to improve the reliability of the temperatures their...
