TV holography is used to measure the components of the deformation vector, whereas TV shearography is used to obtain the derivatives of the displacement components. In this paper, we highlight a novel approach to split the CCD into two parts which enables to extract entirely different information from a single experimental configuration. A holo-shearography configuration provides simultaneous measurement of out-of-plane displacement and its slope change in real time. Similarly a holo-comparative configuration multiplexes an out-of-plane displacement configuration and a comparative interferometric configuration. Few experimental results using both these configurations are presented. In addition TV holography is implemented for vibration studies on an Indian classical musical instrument--Veena. The preliminary studies on a model veena are demonstrated.
