A hyperspectral microscope based on a birefringent ultrastable common-path interferometer (Conference Presentation)

We introduce a Fourier-transform hyperspectral microscope based on an ultrastable birefringent interferometer. The microscope enables wide field acquisition with broad spectral coverage, tunable spectral resolution, high sensitivity and short acquisition time. We present two prototype implementations and an add-on for a commercial microscope. We provide examples of applications in biology and solid state physics.
