Evaluation of the curing process of Ultraviolet (UV) curable adhesive by using phase-shifting digital holography is proposed. In digital holography, interference fringes produced by the reference wave and the object wave reflected from the adhesive film are recorded sequentially as hologram over a period of time and the curing process of adhesive is analyzed from the phase difference of two successive reconstructed complex amplitudes of the object waves. The variation of phase image obtained by digital holography is followed during the hardening process of adhesive. It is shown that the local variation of hardening process can be visualized and analyzed numerically. Experimental analysis is conducted with a constant UV light intensity. Correlation between the UV light intensity and the hardening process obtained by digital holography is discussed in this paper.
