LC-tuned Fourier transform imaging spectrometer

We demonstrate a novel spectral imaging device based on an imaging Fourier transform spectrometer (FTS) with phase delays electro-optically controlled by fast tuning liquid crystal (LC) elements. The electro-optic (EO) tunable multispectral/hyperspectral imaging give the spectral imager significant advantages, including reduction in size and mass for simultaneous 2D spectral imaging, with a high spatial and spectral resolution. The technology is made very attractive for its potential military, medical and remote sensing applications where hyperspectral imaging plays a significant role in detection.
