Abstract
A time series signal multichannel frequency analyzer comprises a Fourier transform lens, a liquid crystal panel disposed at the front focal plane of the Fourier transform lens, means for inputting a time signal from a different signal source to each scanning line of the liquid crystal panel, observation means disposed at the rear focal plane of the Fourier transform lens, and a cylindrical lens disposed between the Fourier transform lens and an observation plane of the observation means.
