Assessment of eggs freshness by means of pulsed infrared thermography
Proceedings of the 2018 International Conference on Quantitative InfraRed Thermography, 2018 The paper examines the topic of identifying eggs freshness through an original approach based on pulsed thermography. The proposed method relies on a short thermal stimulation performed by means of a xenon flash, which rises up the temperature of the egg of less than 1 degrees C.
