Patent ID: 8436310

Claim:
A system for reducing effects relating to stretching of an optical fiber, the system comprising: an optical source, the optical source outputting an optical signal; a terahertz transmitter optically coupled to the optical source, the terahertz transmitter configured to emit terahertz radiation to a sample when activated by the optical signal; an terahertz receiver optically coupled to the to the optical source, the terahertz receiver configured to detect terahertz radiation conditioned by the sample and generate an electrical signal which can be interpreted, scaled and/or digitized by a data acquisition system electrically coupled to the terahertz receiver; a means for providing the optical signal to both the terahertz transmitter and terahertz receiver such that the terahertz receiver is synchronized to the terahertz transmitter by the optical signal; and wherein the means is configured to prevent the stretching or bending of a first optical fiber carrying the optical signal provided to the terahertz transmitter or terahertz receiver.
