Documentation

The CaTSper tool extracts the frequency-dependent optical constants from terahertz time-domain waveforms. It is intended to serve as a simple-to-use but powerful tool for the terahertz time-domain spectroscopy (THz-TDS) community.

Basic Workflow

The process of extracting the spectra from the raw time-domain data involves two separate steps:

cambridgeTHzconverter

Collating the raw sample and reference waveform(s) into a single standardised .thz file. Additional metadata is captured in this file, including, for example, sample thickness, temperature or other contextual information.

catsper

The main CaTSper tool is designed to read the .thz file and carry out all subsequent signal processing steps. The tool can be used to display the time-domain waveform, apply any required truncation to the waveforms, select and apply suitable Fourier transformation parameters and output of the spectra.
