“…Monoclinic biaxial YSO and LYSO crystals belong to the 𝐶2/𝑐 space group symmetry [42], point group 2/𝑚 [29], but the following methodology can be applied in general to any similar monoclinic crystal. The LYSO structural and mechanical properties have been studied also for applications as scintillator in medical devices and high-energy physics [42][43][44]. In the following tables 1 and 2 we list the structural and the optical data which are available to date.…”

We study the elasto-optic behaviour of monoclinic and trigonal crystals. The eigenvalues and eigenvectors of the dielectric impermeability tensor under stress are evaluated by the means of the approximated formulae obtained by Sirotin. The parameters which characterize Bertin's surfaces and fringe patterns in conoscopic observation are determined as functions of either residual or applied stress. Later, the photoelastic constants, and the rotation of the optic plane and optic axes bisector are estimated in order to allow for the evaluation of the residual or applied stress by conoscopic measurements. Finally, we obtain the dependence of the refraction indices on the stress. The knowledge of these crystal properties is mandatory for applications in high physics energy, security, geological prospection and in crystals for photonics and medical applications. The evaluated photoelastic constants allow the development of methodologies for an easy and fast quality control via stress distribution detections by means of conoscopic observation, even for strongly anisotropic crystals. As a case study we apply these results to the cases of monoclinic Lu 2(1−𝑥) Y 2𝑥 SiO 5 (LYSO) and trigonal LiNbO 3 (Lithium Niobate).

“…As far as we known, the unique refraction index measured for (LSO) is given in [17] and is . However, the principal refraction index for YSO crystal can be found in [13], and with respect to the frame they are: moreover, in [18], the direction was identified, in LYSO samples with , with the crystallographic direction [ 1, 0, 4] whereas the monoclinic -axis is directed as . Accordingly, by using as an example the YSO data from [13] with the optic axis taken from [18] we get:…”

In order to obtain a complete characterization and understanding of the structural, optical and mechanical properties of LYSO scintillanting crystals, we studied a mechanical, optical and photoelastic model for a cylindrical prism of square cross-section bent by applied loads. This is the starting point which is necessary in order to design a set of mechanical, electrical and optical experiments aimed to obtain the characterization of the macroscopical behavior of LYSO and similar crystals.
