Coating thickness is a critical parameter in many industrial applications. For instance, in the aerospace and automotive industries, coatings are used to protect components from corrosion and wear. Inadequate coating thickness can lead to premature failure, safety risks, and costly repairs. Similarly, in the construction industry, coating thickness affects the durability and aesthetic appeal of buildings. Therefore, accurate and continuous coating thickness measurements are essential to ensure product quality, reliability, and performance. in the construction industry
