Fourier Transform Micro Spectrometer Based on Spatially-Shifted Interferogram Bursts

Description

A spectrometer with improved resolution includes a spectral domain modulator having a periodic response in the spectral domain to modulate a wideband source spectrum and cause one or more shifted bursts in the interferogram.

Aspects

The present invention relates in general to spectrometers, and in particular to Fourier Transform micro spectrometers. Embodiments of the present invention provide a spectrometer with improved resolution. The spectrometer includes a spectral domain modulator having a periodic response in the spectral domain to modulate a wideband source spectrum and cause one or more shifted bursts in the interferogram. The spectrometer can be very compact and monolithically integrated.
