I have posted my first version of the chapter on how to build a FTIR
screen here:

Hi Laurence,
That's great, thanks. One thing - could you do a little introductory
paragraph explaining the technology behind FTIR to accompany that
diagram of the setup you have at the beginning? I think that would
help clarify later sections of the chapter for readers.

Hi,

I've updated my document at: http://docs.google.com/Doc?docid=dhk2vwgk_4jdj5d8g2&hl=en

If you need the higher resolution of the images, let me know. It is
also required to change the figure numbers in this document.

Kind regards,
- Laurence
