A dispersive compact Fourier transform spectrometer is realized which operates in the visible wavelength range. No moving parts, no imaging system and compactness are the characteristics of this spectrometer. It is based on a novel beam splitter design, which reduces the influence of the size of the light source and therefore the spatial coherence requirements. The effect of dispersion due to an...

The helical pitch of the cholesteric liquid crystal (CLC) can be adjusted to reflect the colors red, green, and blue. Additive mixing of these colors in displays results in multicolor images and it is easy to use pure primary blue and green colors, but the red color is in general very unsaturated. We show by simulations that this poor red color performance is due to reflection sidebands on the...
