Abstract
"SISTEMA DE MEDIçãO DE REDES PASSIVAS DE SENSORES DE FIBRA óPTICA". O qual permite a medição de redes de sensores de fibra óptica em redes ópticas passivas, mediante a utilização de lasers sintonizáveis de semicondutor operando em regime de onda contínua. Precisamente o laser sintonizável (2), com seu respectivo controlador (3) e através de um circulador (4), envia sinais de uma determinada longitude de onda à rede passiva (1) de sensores ópticos durante um período T1, depois do qual muda de longitude de onda, recebendo os sinais refletidos na rede de sensores em um conversor eletro-óptico (6), preferivelmente através de um filtro (5) de faixa eliminada, que rejeita a faixa 'off'."FIBER OPTIC SENSOR PASSIVE MEASUREMENT SYSTEM". This allows the measurement of fiber optic sensor networks in passive optical networks by using tunable semiconductor lasers operating in continuous wave regime. Precisely the tunable laser (2), with its respective controller (3) and through a circulator (4), sends signals of a certain wavelength to the passive network (1) of optical sensors during a period T1, after which it changes of wavelength, receiving the signals reflected in the sensor network in an electro-optical converter (6), preferably via an eliminated band filter (5), which rejects the 'off' band.
