Two-dimensional fourier transform spectrometer

A method of measuring a spectrum having a plurality of dimensions comprising:

• coupling a collinear sequence of light pulses onto a medium;
• coupling an optical signal onto the medium, the optical signal being modulated by the sequence of light pulses to form a modulated light signal;
• dispersing the modulated light signal;
• detecting the dispersed modulated light signal to provide spectral data;
• and
• forming a spectral representation from the spectral data having a plurality of dimensions.

A system for generating spectral data having a plurality of dimensions comprising:

• a light source that emits light;
• an optical system coupled to the light source that directs a collinear pulse sequence onto a medium;
• an optical signal that is optically coupled to the medium to modulate light directed onto the medium;
• and
• a detector that detects a modulated optical signal to provide spectral data having a plurality of dimensions.

A pulse modulation system comprising:

• an optical system that directs a collinear pulse sequence onto a medium;
• an optical signal that is optically coupled to the medium to modulate light directed onto the medium;
• a pulse modulation system to modulate at least one light pulse incident on the medium;
• and
• a detector that detects the modulated optical signal to provide a spectral data having a plurality of dimensions.
