Patent ID: 8457915

Claim:
A system for interpreting a terahertz waveform, the system comprising: a 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; a first optical interface providing optical interference to the pulse of terahertz radiation, wherein the first optical interface will reflect a first optical interface reflected portion of the pulse of terahertz radiation to the terahertz receiver; a second optical interface providing optical interference to the pulse of terahertz radiation, wherein the second optical interface will reflect a second optical interface reflected portion of the pulse of terahertz radiation to the terahertz receiver; an etalon spacing being defined between the first optical interface and the second optical interface, the etalon spacing being configured to receive a sample to be irradiated by the pulse of terahertz radiation; and wherein the sample will reflect a first sample reflected portion of the pulse of terahertz radiation to the terahertz receiver and a second sample reflected portion of the pulse of terahertz radiation to the terahertz receiver.
