Hollow waveguides for sensor applications
Abstract
Hollow waveguides offer applications in remote thermometry and spectroscopy because they transmit infrared radiation and possess chemical and mechanical durability, coupled with high melting points. As in solid dielectric optical fiber, the radiation is propagated by total internal reflection when the refractive index of the cladding is less than that of the air core (n
