Application Of Holographic Interferometry To The Study Of Structural Deformations In Civil Engineering
Jean-Marie Caussignac · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1978
Evolving construction techniques in civil engineering during recent years have favoured the concomitant and growing extension of complex structures. The design of these structures most often calls for the introduction of basic assumptions which greatly condition the results. In certain cases difficult to analyse, it is particularly desirable to be able to infirm or confirm, on the is of other methods, the validity of the assumptions made .It is thuspossible to examine more closely the behaviour of these structures under load. In particular, the optical methods of stress analysis can help to facilitate the interpretation and utilization of design calculation data. Among the optical methods available to us, we endeavoured to develop in a quanti tative manner the use of holographic interferometry for application to certain civil engineering problems.
