Abstract
We present designs of static Fourier transform spectrometers that are based on a Wollaston prism with a large field of view. Besides the usual advantages of static Fourier spectrometers (large resolving power, large wave-number range, high throughput), these designs also present the advantage of using relatively cheap liquid-crystal technology. The use of twisted liquid-crystal structures gives a large field of view, which in turn gives the ability to collect more light from a divergent light source. Measurements are compared with simulations. Different simulation principles are used. We found new configurations by using twisted structures that show a large field of view.
