SYSTEM FOR DETERMINING AT LEAST ONE PROPERTY OF A SHEET DIELECTRIC SAMPLE USING TERAHERTZ RADIATION

摘要

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 tera-hertz 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.

1. A system for determining at least one property of a sheet dielectric sample using terahertz radiation, the system comprising:
at least one terahertz transmitter configured to output a pulse of terahertz radiation to the sheet dielectric sample; a terahertz receiver configured to receive at least a portion of the pulse of terahertz radiation from the sheet dielectric sample, wherein the terahertz receiver is configured to output a measured waveform based on the terahertz radiation received by the terahertz receiver; a control unit in communication with the terahertz receiver and configured to receive the measured waveform from 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, anddetermine the at least one parameter of the model waveform so that the model waveform best matches the measured waveform.
