The success of such a tests deeply depends on the instrumentation recording the response parameters. The expense could be high enough depending on the required response and the extent of the specimen to be tested. This paper proposes the application of optical methods for response estimation as an alternative to traditional instrumentation: i) for static tests, a Fourier based method to estimate strains and displacements, and ii) for dynamic tests, the use of a system of optoelectronic cameras to estimate displacements and accelerations. Several static and dynamic tests were performed to validate this proposal. These tests were instrumented with LVDTs, accelerometers, strain gages and extensometers. The results show a good agreement between the proposed methods and the reference results and prove that these methods have the potential for replacing or for being a complement of traditional instrumentation, while give more significant information with reduced costs.
