EL 亮度由投资回报率内的平均灰度决定。在这种情况下，EL 亮度可以在

EL brightness is determined by the average gray level within the return on investment. In this case, the EL brightness can be averaged according to the purpose on the overall illumination area or subset window. For local detection of damage, a subset window can be used because the subset grid corresponds to the spatial representation of the specimen. In contrast, the overall lighting area captures the damage and absolute health of the specimen. This research focuses on the correlation between EL brightness, strain, and resistance changes: Therefore, the damage location aspect is not studied to reduce complexity. The obtained EL brightness data is displayed in gray scale units. To convert the grayscale digital unit to a physical light-emitting unit, physical reference light source: commercially available EL tape strip (blue electroluminescent tape, 100 cm, 40 cd/m2, 10 nF per meter, Adafruit) for the same lens and collection Set up.

EL brightness is determined by the average grayscale within ROI. In this case, the EL brightness can be averaged according to the purpose on the overall illumination area or subset window. For local detection of corruption, you can use a subset window because the subset mesh corresponds to the spatial representation of the specimen. In contrast, the overall lighting area captures the damage and absolute health of the specimen. This study focuses on the correlation between EL brightness, strain, and resistance changes: therefore, damage positioning is not studied to reduce complexity. The EL brightness data obtained is displayed in grayscale units. To convert a grayscale digital unit to a physical light emitting unit, the physical reference light source: commercially available EL tape strips (blue electroluminescent tape, 100 cm, 40 cd/m2, 10 nF per meter, Adafruit) for the same lens and acquisition settings.
