A new optical technique based on color holographic interferometry is presented in this paper. Experiments on color interferometry in real time and by double exposure are carried out using three coherent wavelengths (blue, green and red) produced by c.w. lasers. Holograms are recorded on single-layer panchromatic silver-halide Slavich PFG 03C plates. As an example, a photograph of a colored Lippmann- Denisyuk interferometric hologram is presented, showing the mechanical deformations of a metallic sample. A video film on real-time trichromatic interferometry is presented. The video film, recorded at 25 frames per second, shows colored interference fringes produced by phase objects.
