Super resolution spectral imaging of the imaging-type 2D Fourier spectroscopy based on the dark field image

Abstract

We proposed the imaging-type 2D Fourier spectroscopy that has the phase shifter on the Fourier transform plane. The objective lights from the transmissive component and the scattering component of the measurement object are dispersed on the different area of the Fourier transform plane. So, by introducing the spatial filter, we can observe only the spectral characteristics of the scattering component light. Because of the dark filed image, the super resolution spectral imaging for the super fine particle can be realized.
