Time resolved Fourier transform spectroscopy
|
||
|
Our instrument is able to routinely record high information time-resolved Fourier transform (TRFT) interferograms. The instrument is based on the LPPM stepping mode ( step scan ) Connes-type interferometer. Spectral- and time-resolution limits are respectively equal at best to 2.5 10-3 cm-1 and 2 ns. High resolution TRFT spectra are recorded in the infrared and visible spectral range. |
