This technique probes the properties of a material with short pulses of terahertz radiation. The radiation of the sample is detected and modulated in the MHz frequency range. An optical system driven by one or more lasers is producing chopped THz pulses which can be measured and detected with the lock-in amplifier.
|Objectives:||performing synchronous detection of the reflected radiation by gaining amplitude and phase information of the signal
|Benefits:||the HF2LI provides a programmable instrument architecture that runs a powerful graphical user interface and permits to run any number of dedicated software tools in parallel for application settings or readouts|
|Relevant products:||HF2LI, HF2LI-UHS|
