An overview of the applications of holographic interferometry for spacecraft structural components at ISRO Satellite Centre, Bangalore, India, is presented. The details of the development of a dual vacuum stressing technique and its application for holographic nondestructive testing (HNDT) of honeycomb panels are presented. Results of some calibration studies conducted for HNDT of propellant tanks are also presented. It is found that holographic interferometrie is quite useful, particularly for HNDT of honeycomb panels and propellant tanks used for spacecraft structural components.
