IRSPEC enables the on-line acquisition of the signal given by a far-infrared Michelson Interferometer. It, simultaneously, computes the data Fourier transform after apodisation and displays the results. Many calculation loops, using all the data points every time, allow the user to observe the spectrum evolution and eventually to stop acquisition.

As soon as the wanted data have been completed (max. 2048) IRSPEC computes the final coefficients of spectrum (max. 200) and displays permanently the result which can then be printed or plotted. A reference spectrum can be stored to compute, from a sample spectrum, transmission (I/1.) or absorbance (log (I./1) ).

Documentation for the program is written in French.
