The real time technique of time averaged holographic interferometry has been applied to determine the natural frequencies and the corresponding mode shapes for the transverse vibrations of clamped circular plates with a straight eccentric narrow slit. Eccentricity and length of the slit have been selected as parameters, while width of the slit has been kept to be constant. The first six natural modes are discussed. Most of the natural frequencies show a decreasing tendency as the slit length increases, and the tendency becomes larger when the slit coincides with, or is parallel to one of nodal diameters. The change of the natural frequencies with the slit eccentricity varies with each mode, and especially that of the higher modes than the third mode cannot be found any regularity.
