Abstract
Official abstract text for this publication.
A multidimensional spectrometer encodes frequency information into laser pulses so that a frequency insensitive detector may be used to collect data for a multi-dimensional spectrograph only from intensity information and knowledge of a modulation providing the encoding. In one embodiment the frequency encoding may be done by a conventional interferometer greatly simplifying construction of the spectrometer.
First claim
Opening claim text (preview).
We claim: 1. A multi-dimensional spectrometer comprising: a first spectral modulator producing at least one first modulated light pulse passing along a first optical path, the first modulated light pulse formed from an interference of two substantially identical pulses providing modulation by interference between the identical pulses; a second spectral modulator producing at least one second modulated light pulse passing along a second optical path, the second modulated light pu…
