An electro-optical measurement system for the DC characterization of visible detectors for CMOS compatible vision chips is presented which can help designers to characterize these detectors. The measurement system has been designed to be versatile, fast and easily expandable and used. Two different set-up's for the measurement of the spectral response and the optical dynamic range of the detect...

This article deals with an original haptic teleoperation and human–robot interaction (HRI) for microrobotic tasks involving optics more generally light information. It aims to demonstrate the proof of concept using information in component alignment submicrometer accuracy. The case study focuses on a laser optical fiber active surface photodiode system pantograph. Since error <inline-formula xm...

In practical sensor applications it is advantageous for the sensor material to be a solid. Yet, even for the simplest intramolecular processes, where no bonds are broken or formed, reactions are generally different in fluids than in solids. For example, in the case of photoexcitation of a molecule and its return to the ground state, the rates of the processes are strongly dependent on the mediu...

Electrooptical devices and optical communications need compounds with second-order nonlinear (NLO) properties as construction blocks. Typically, to show a large quadratic hyperpolarizability, compound should be asymmetric, characterized by variation between the dipole moments in excited ground states, have low energy electronic transitions. For example, hyperpolarizability can reached when an e...
