abstract

• Due to the increase in the incidence of cracks in a specific model of side-view mirrors provided with an anti-fog thermal resistance, the heating process of the mirror was analyzed using an infrared camera and the results were compared to a different model that had a very low incidence of cracks. The heating velocity and temperature distribution over both sets of mirrors was tested by recording the video output from an infrared camera while the mirrors were heated up with its internal heating resistance. The thermal videos showed that the model that cracked frequently had a higher temperature, an uneven temperature distribution and reached its highest temperature faster than the model that did not crack easily. These findings show that the design of the thermal resistance used to heat mirrors as an anti-fog technique has an influence on the quality and durability of rear view mirrors.
