In this paper a distributed intelligent system for civil engineering structures on-line measurement, remote monitoring, and data archiving is presented. The system consists of a set of full-field optical displacement sensors connected to a controlling server. The server conducts measurements according to a list of scheduled tasks and stores the primary data or initial results in a remote centralized database. The description of an exemplary set of full-field sensors including IP and thermovision camera, 2D and 3D digital image correlation systems, and grating interferometry based extensometers is provided. Three different measurement tasks performed by means of this systems are presented in details.

Today there exist different commercial micro-optics measurement instruments for the characterization of micro-optical components and microlenses in particular. However there is often a lack of a complete quantitative optical characterization of the latter components. Therefore we will focus in this paper on the optical characterization of all types of refractive microlenses, more in particular spherical and aspherical microlenses. Moreover the results of the performed round robin within the European 6th FP Network of Excellence on Micro-optics "NEMO" will allow us to select the most appropriate instrumentation tools for characterizing refractive microlenses.
