Paper Abstract
Digital holographic techniques to investigate drying processes of both paint films and ink dot is presented. The proposed
technique based on digital holographic interferometry can achieve both visualization of variations and analysis of
dryness of paint films in the drying process by using phase changes between two subsequent reconstructed complex
amplitudes of the reflected light from the film. To follow the drying processes, holograms are recorded at a constant time
interval. Phase-shifting digital holography has been applied to analyze the dryness of commercial paints applied on the
metal plate. For analysis of an ink dot having diameter of a few hundred micrometers, digital holographic microscopy is
applied to evaluating the time history of dryness of ink dot in the drying process. This paper describes these holographic
techniques applied to the commercially available paint and ink and presents some experimental results.
