    Abstract: The present invention is directed to systems and methods which utilize a cavity ring-down spectroscopy (CRDS) technique implemented for the measurements of vapor transmission rate. In one embodiment, the vapor content to be measured is contained within an optical cavity. Light is then injected into the cavity up to a threshold level and the decay time of the injected light is measured. When the wavelength of the injected light is resonant with an absorption feature of the vapor the decay time increases linearly as a function of vapor content. In this manner, vapor content causes a longer decay time and thus the amount of vapor passing through the film (film permeation rate) can be determined in real-time.

    Abstract: Provided is an optical sensor interrogation system. The optical sensor interrogation system includes: a light source unit which matches round-trip time of light and wavelength tunable cycle time of light in a resonator and emits light; a sensing unit which receives an optical signal in which a center wavelength periodically tunes, from the light source unit and tunes the center wavelength of the optical signal according to physical changes applied from the outside; and a signal processing unit which receives the optical signal reflected from the sensing unit, detects data, and images the data. In particular, the light source unit includes a delaying unit which delays the round-trip time of light and a tunable filter which tunes the wavelength of light so as to match the round-trip time of light with the wavelength tunable cycle time of light. Accordingly, a Fourier domain mode locking (FDML) wavelength swept laser, which operates at speed of several tens kHz or above, is used as a light source so that strain of a fluid, which changes in a short time interval of 0.1 msec or below, is precisely measured and thus a real-time analysis may be performed at high speed.
