I have constructed a kitchen table prototype of the fiber agitator described in this paper https://arxiv.org/pdf/1802.01642.pdf.

This link shows it in action while testing. It will have a cover to stop my Burmese cat playing with it!

I will post results when I have them.

Here are some results with my Hi Res Spectrograph R ~2300 using tungsten flats. These images have a strong contrast stretch to highlight the difference.

I will be putting the new agitator into production.
