Abstract

na detecção de fibra óptica distribuída dentro de um furo, a precisão dos canais de sinal de correlação com a profundidade ao longo do furo pode ser melhorada levando em conta o efeito termo-óptico na velocidade de grupo da luz. em uma aplicação de exemplo, isso permite, por sua vez, localizar com mais precisão as fontes acústicas por meio de sensor acústico distribuído. são apresentadas modalidades adicionais.
