Terahertz spectroscopy signal acquisition instrume

The terahertz spectral signal acquisition instrument integrates the control circuit, signal processing and acquisition circuit modules to build a terahertz time domain spectrometer. Users do not need to design the circuit and do not need programming, so they can easily control the fast sweep motor ,slow sweep, imaging motor, adjusting optical path, offset transmitting antenna and other modules, then collect the signals of the receiving antenna and complete the terahertz time domain spectrometer system required for construction.


Features


The application is simple and flexible, and users can quickly build the required system.


Modular product design, including quick-sweep module, slow-sweep module, imaging module, etc.


Users can take advantage of existing resources such as femtosecond lasers, terahertz antennas, and more.


Portable design with touch screen operation.


The upper computer is equipped with control software and analysis software, and the control software coordinates the system work, and easily acquires spectral line information or performs imaging scanning; the analysis software can perform in-depth analysis on spectral line data or imaging data.
