Abstract
"ACELERÈMETRO óPTICO". é descrito um acelerómetro óptico contendo redes de Bragg para a medição de vibrações mecânicas com base no princípio de um sistema massa-mola-amortecedor, o acelerómetro compreendendo basicamente um módulo 100 com corpo 110, uma massa sísmica 120 que reage a uma aceleração, uma placa metálica 130 que atua como elemento de sustentação, e elemento de mola constituído por uma única fibra óptica 140 contendo redes de Bragg 150. Alternativamente um módulo 200 com corpo 210 compreende uma haste 216 posicionada eqüidistante às laterais verticais 213 do dito corpo. O acelerómetro óptico descrito pode ser usado para a medição de vibrações mecânicas em uma, dois ou três direções."OPTICAL THROTTLE". An optical accelerometer containing Bragg networks for measuring mechanical vibrations based on the principle of a mass-spring-damping system is described, the accelerometer basically comprising a module 100 with body 110, a seismic mass 120 that reacts to an acceleration, a metal plate 130 acting as a support element, and spring element consisting of a single optical fiber 140 containing Bragg nets 150. Alternatively a module 200 with body 210 comprises a rod 216 positioned equidistant to the vertical sides 213 of said body. The optical accelerometer described can be used to measure mechanical vibration in one, two or three directions.
