An interferometer Fourier transform spectrometer, having increased speed, is capable of performing a Fourier transform in parallel, in analog form, using a weighted matrix. The spectrometer includes a linear detector array responsive to an interferogram. The detector array is coupled to a plurality of integrating sampling amplifiers. Each column of a group of columns of the matrix is coupled in parallel to a respective integrating sampling amplifier, and the output signals from each row of a group of rows form an output signal array.
