CTinHS Lecture 2/2022: Principles of holographic interferometry for non-destructive subsurface examination
The CTinHS lectures are part of HS Academy: a collaborative initiative between IPERION HS (www.iperionhs.eu) and E-RIHS (www.e-rihs.eu). The two European projects integrate facilities of recognized excellence in Heritage Science, offering access to a wide range of high-level scientific instruments, methodologies, data, tools and training opportunities for advancing knowledge and innovation in the field.
The second lecture of the “Current Topics in Heritage Science” series will be delivered by Dr. Vivi Tornari. She is a senior expert in Optics/Holography/Interferometry and Optical system development, founder of Applied Holographic Metrology for Cultural Heritage and creator of DHSPI-Digital Holographic Speckle Pattern Interferometry portable system. She will speak online in the “Current Topics in Heritage Science” series on Thursday, October 20th, at 3 pm (Rome time).
Lecture #02 is focused on the basic principles and prominent applications of Holographic Interferometry non-destructive examination of movable and immovable heritage objects. The invited expert will illustrate the fundamental aspects of the theory and will also present the working principle of the remote access portable custom designed scientific instrument – Digital Holographic Speckle Pattern Interferometry (DHSPI). Some recent real case applications will be shown to illustrate the current advancements and limitations, as well as future potentials of the methodology. The lecture is a lifelong learning opportunity and is open to both experienced and emerging professionals, experts in the field as well as students, colleagues, researchers and practitioners.
