Opto Lab

• Interferometric techniques (speckle, moiré and holography) are applied to stress/strain analysis
of electronic components, biological specimens and industrial components, reconstruction of
3-D shape of objects, evaluation of thermal distortions and residual stresses, identification of
constitutive behavior of materials with high nonlinearities (e.g. biological membranes).
• Nanosciences: nanolography, roughness measurement with nonconventional illumination
(e.g. evanescent fields), measurement of strains of crystalline arrays (at dislocation level).
• Gradient-based (SLP, SQP and modified feasible directions) and metaheuristic optimization
algorithms (simulated annealing, harmony search, big bang-big crunch, firefly algorithm, heat transfer search) have been developed for sizing and layout optimization of large-scale skeletal structures, preliminary design of liquid hydrogen tank, and hybrid methodologies for mechanical characterization of materials (composites, biotissues, cells).
