    Abstract: A system for determining at least one property of a sheet dielectric sample using terahertz radiation includes at least one terahertz transmitter configured to output a pulse of terahertz radiation, a terahertz receiver configured to receive at least a portion of the pulse of terahertz radiation, wherein the terahertz receiver is configured to output a measured waveform based on the terahertz radiation received by the terahertz receiver, and a control unit in communication with the terahertz receiver. Wherein the control unit is configured to choose at least one region of interest of the measured waveform, compare the at least one region of interest of the measured waveform to a model waveform, vary at least one parameter of a model waveform to minimize the difference between the model waveform and the measured waveform.

    Abstract: A system for dispersion compensation in a terahertz system includes an optical fiber configured to transmit an optical pulse, a compensator optically coupled to the optical fiber, the compensator configured to compensate for a dispersion of the optical pulse caused as the optical pulse propagates through the optical fiber, and an optically induced terahertz device optically coupled to the compensator, whereby the optically induced terahertz device is configured to transmit or receive terahertz radiation.

    Abstract: A system and method for detecting anomalies concealed upon a person may include a detection probe having an electromagnetic transmitter and an electromagnetic receiver. The electromagnetic transmitter is configured to emit electromagnetic pulses, while the electromagnetic receiver is configured to sample electromagnetic pulses from the electromagnetic receiver at specified times within a waveform window. The electromagnetic pulses may span the terahertz spectral region of 0.04 to 4 THz. The system may also have optical fibers connected to the electromagnetic transmitter and electromagnetic receiver, wherein femtosecond laser pulses are directed from a source to the electromagnetic transmitter and the electromagnetic receiver by the optical fibers.

    Abstract: A system for reducing effects relating to stretching of an optical fiber includes an optical control source, the optical source outputting an optical signal, a terahertz transmitter and receiver both being optically coupled to the optical source, and 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. The means prevents the stretching of an fiber carrying the optical signal provided to the terahertz transmitter or terahertz receiver or allows for the stretching an optical fiber such that the terahertz receiver will still be synchronized to the terahertz transmitter by the optical signal.
