Moire´ interferometry is a full-field optical method that has high displacement, strain and spatial resolution. The method has been used extensively for deformation analyses in the various fields of mechanics. Special considerations arise when deformation measurements of tiny specimens or tiny regions of larger specimens are sought. The relative displacements within a small field of view will be small (even if the strains are not small), so the number of morie´ fringes might not be enough for an accurate analysis.

The Creation

The poem ‘Ushshaq-nama by Fakhr ad-Din ‘Iraqi (610–688 / 1213–1289) is the first poetical writing on the subject of mystical love in Persian literature. ‘Iraqi’s authorship of this work has never been questioned by researchers. However, the English orientalist J. Baldick 1973 cast a doubt on ‘Iraqi’s authorship of this poem. The article examines in detail the arguments of J. Baldick both from the point of view of the context of the creation of the poem, as well as the methods of the latest computational methods, in particular stylometry. Boldik's arguments concern both the historical and religious context in which ‘Iraqi lived and the peculiarities of his works, primarily the poem‘Ushshaq-name. The paper demonstrates that this computational method may be used for the study of the features of the style of Persian poetry and the confirmation of the authorship of doubtful Persian writings. Further expert decision full-field by Artjoms Šeļa based on stylometric methods for the establishment of the poem ‘Ushshaq- nama is expounded. While the results of the analysis of the historical and religious contexts of the poem may serve as confirmation of the authorship of ‘Iraqi and the refutation of the Baldick hypothesis, the results of the stylometric analysis do not give an unambiguous answer to the question of its authorship.

Deformation Measurements

This paper compares the technology and the performances of three ultra high speed cameras for full-field deformation measurements with Digital image correlation or the grid method. The three cameras are based on multiple CCD sensors (Cordin 550-62, with rotating mirror or DRS IMACON 200 with gated intensified CCDs) or dedicated chip (Shimadzu HPV). The advantages and limitations of these cameras are critically reviewed.
