Abstract

Patente de Invenção: <B>"PROCESSO DE MEDIR A TENSãO DE TREFILAçãO DE FIBRAS óPTICAS''<D>. Um processo de medir a tensão de trefilar uma fibra óptica por intermédio da forma de onda de oscilação da fibra óptica sendo trefilada de acordo com a invenção pode de forma exata, confiável e fácil detectar uma frequência de pico no espectro de frequência de uma forma de onda de oscilação sem ser afetado por ruído. Com o processo de medir a tensão de uma fibra óptica sendo trefilada pelo determinar a frequência de oscilação fundamental da fibra óptica a partir de um valor máximo no espectro da forma de onda de oscilação linear da fibra óptica, a detecção de uma frequência de pico no espectro de frequência de uma forma de onda de oscilação linear compreende etapas de conduzir uma operação de detecção inicial através de uma gama de frequência prevista conter uma frequência de pico e conduzir subsequentes operações de detecção através de respectivas gamas de frequência obtidas pelo sequencialmente alinhar a frequência média com a frequência de pico detectada na operação de detecção imediatamente precedente.
