Abstract
Official abstract text for this publication.
Methods and apparatus for the active control of a wavelength-swept light source used to interrogate optical elements having characteristic wavelengths distributed across a wavelength range are provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: providing light, wherein a wavelength of the light is changed according to a sweep function; interrogating one or more optical elements with the wavelength-swept light to produce optical signals; filtering the optical signals, wherein a bandpass wavelength range is changed based on the sweep function to follow the changes in the light's wavelength; and receiving the filtered optical signals for processing. 2.…
