Opis:: The advances in the design and fabrication of microlaser arrays, photodetectors, and free-space optical interconnection elements have driven the creation of ever more "real world" demonstrator systems. In this paper we review the progress made to date on two separate demonstrator projects which have been assembled at Heriot-Watt University. We shall describe some of the enabling technologies used in the creation of these systems and outline the potential for scaling the architectures described up to sizes where the computational advantages of the optics-in-computing paradigm become highly attractive.

Opis:: In this study, an artificial neural network model was established by using experimental measurement values obtained from a low-speed subsonic wind tunnel, with the length of 75 cm and experiment test section of 32× 32 cm². Model results were compared with experimental values and then, the prediction was made for the unmeasured tunnel stream values. In the wind tunnel, the jet velocity of 25 m/s and four tunnel velocities of 0, 5, 10 and 20 m/s were used. At four measurement stations x/D=0.3, x/D=12.5, x/D=31.2 and x/D=50, experimental measurements were made using a hot wire anemometer. This study is the continuation of the work done by Inan and Sisman [T. Inan, T. Sisman, Acta Phys. Pol. A 127, 1145 (2015)]. Inner grooved circular jet flows at x/D=0.3 and x/D=50 stations with average tunnel flow velocities of 7.5 m/s and 15 m/s were studied by using artificial neural networks.

Opis:: The optical coherence tomography is an optical measurement technique used for investigation of wide range of scattering or semitransparent materials. The optical coherence tomography enables surface and subsurface examination of different types of materials to be performed in non-contact and non-destructive way. Our research have been concentrated on optical coherence tomography systems with polarization sensitive analysis. Such a combination of optical measurements methods improves optical coherence tomography visualization contrast and also delivers some extra information about investigated devices. However, applying polarization sensitive analysis is associated with problems related to the use of ultra broadband optical sources. We have managed studies on the improvement of signal processing method. According to obtained results the problem of signal processing method in polarization sensitive optical coherence tomography can be solved by the use of the spectroscopic analysis. In this paper we present a brief discussion about the polarization sensitive optical coherence tomography measurements supported by spectroscopic analysis of backscattered light from investigated device.
