Multiwavelength rainbow holographic interferometry.
Although the two-step rainbow holographic process of Benton [S. A. Benton, J. Opt. Soc. Am. 50, (1969)] offers a significant improvement in holographic displays, its scientific applications are somewhat limited. It is primarily due to the awkardness of the two-step process. We have demonstrated [H. and F. T. S. Yu, Opt. Lett. 2, 85 (1978)] a one-step process which greatly simplifies the procedure in making rainbow holograms. In this paper, the applications of the one-step process to holographic interferometry is demonstrated. A unique multiwavelength holographic interferometric technique is also introduced. This multiwavelength process enables the study and comparison of more than one physical effect. The holographic interference fringe patterns due to different effects can be displayed individually, or together different colors. This capability further extends the usefulness and versatility of holographic interferometry.
