The possibilities of multicolor digital holographic interferometry are experimentally studied upon measuring displacements of a surface in radiation of a picosecond Nd:YAG laser with the radiation frequency conversion into harmonics (λ1 = 1.06 µm, λ2 = 0.53 µm, and λ3 = 0.35 µm). It is shown that three-color digital holographic interferometry makes it possible to increase the measurement accuracy of displacements. The peculiarities of multicolor digital holographic interferometry by picosecond pulses are discussed.

    As many high-intensity ultrafast-optical measurements involve more than one pulse-typically one to excite a medium under study and another to probe it--a technique for measuring two pulses simultaneously is highly desirable. In two decades, two-pulse measurement techniques have advanced from...
