Abstract
A paint drying process of a three dimensional surface is assessed by phase-shifting digital holography. In the method, it is possible to visualize and to evaluate local variations of drying without any contact on the object and imaging system. In addition, a quantitative analysis utilizing the amplitude and phase changes derived from the reconstructed complex amplitudes of the reflected light from the paint surface is performed and the time of tack-free drying of the paint under different temperature is investigated by comparing the microscopic monitoring and conventional gravimetric methods.
