    Assessment of a Dual-Wavelength Compensation Technique for Displacement Sensors Using Plastic Optical Fibers

    No full text
    The paper analyzes the performance of a dual-wavelength technique devised to compensate power fluctuations in intensity-modulated plastic optical fiber sensors, which were specifically conceived for the measurement of displacements in industrial and civil applications. These sensors retrieve the displacement from the variation of the attenuation along the light path and use two signals at different wavelengths to compensate for the effects of parasitic quantities, such as temperature and strains along the fiber. The theoretical behavior of the compensation technique is presented, and the results of experiments carried out with different combinations of signal wavelengths and plastic fibers are reported. The experimental setup has proved that, by proper choice of the compensation signal wavelength, it is possible to monitor displacements in the range (0 to 10) mm, even for low received power and under severe perturbation conditions, thus significantly improving the long-term stability of the sensor

    A Fiber Optical Sensor For Non-Contact Vibration Measurements

    No full text
    This paper describes an intensity based optical sensor for the evaluation of accelerations from non-contact displacement measurements. Plastic optical fibers are used to collect the reflected light from several points on the vibrating surface, allowing the reconstruction of the vibration distribution. Two compensation techniques to reduce systematic effects due to the target reflectivity are also described and compared: one is based on the spectral analysis of the received optical signal and the other takes advantage of a reference displacement sensor. Experimental results in real conditions during vibration tests have demonstrated the capability to measure sub-micrometer vibration amplitudes up to about 40 kH

    LEYLA BEATRIZ PERRONE-MOISÉS REVISITA A “MARIA ANTÔNIA”: HISTÓRIA ORAL, MEMÓRIA E REPRESENTAÇÕES

    No full text
    O artigo analisa como documento uma entrevista de história oral de vida acadêmica realizada com a Profa. Dra. Leyla Perrone-Moisés. Investiga-se a maneira como a memória narrativa da Profa. Perrone-Moisés reconstruiu suas experiências nas décadas de 1950 e 1960 enfatizando o papel central da “Maria Antônia”, nome dado ao prédio que sediava a Faculdade de Filosofia, Ciências e Letras da Universidade de São Paulo. Em diálogo com a hermenêutica de Ricoeur, sustenta-se que a teoria do conhecimento em história oral pode colaborar para a elaboração de problematizações em torno da memória narrativa, compreendendo-a como fruto de um sujeito engajado na experiência histórica, nas suas relações com o outro e com o tempo
