Abstract
A system and method for forming a low cost optical sensor array. The sensor includes an optical fiber; a first nanocomposite thin film along at least a portion of the optical fiber for interrogating a first parameter through a correlated signal having a first wavelength; and a second nanocomposite thin film along at least a portion of the optical fiber for interrogating a second parameter through a correlated signal having a second wavelength different from the wavelength of the first parameter.
