TSL1401 lust

Hi guys,
http://www.parallax.com/StoreSearchResults/tabid/768/List/0/SortField/4/ProductID/566/Default.aspx?txtSearch=linear+array+sensor
I have to admit... I have pure techno lust and a few questions. But before I ask my questions... let me explain that I'm in
the process of redesigning all kinds of ophthalmic equipment so that the equipment can be built and supported in emerging economies... so far, I'm on the right track and don't need any help...but now I'm thinking about spectral domain oct and
I'm going to need a little help.
I'm going to be using the TSL1401 for sure. The only issue is how many places/ways I use it.
One place that I am going to use it for sure is to control a little rotating mirror... without using a galvanometer.
The other place is in the oct data stream... I don't know this for sure, because I haven't gotten that far.
What is the maximum burst data rate using the TSL1401 and a single Prop I? ... I know I could do the math... but that would produce the wrong answer[noparse]:)[/noparse]
and B
where can I get really cheap pentagonal mirrors that are already in a fixture suitable for really nice rotations?
Thanks
Rich

there are two flavors... time domain and spectral domain
in time domain, structural info is obtained by indexing an interferometer through the z axis... perpendicular to the target. The return light is then combined with a reference beam to get a set of distance measurements and intensity of reflection at each distance.
In spectral domain... the fact that light spreads (in tissue and through lenses) as a function of its wavelength is used to obtain info in the z axis in a one shot approach. Returning light is then combined with the reference beam and then separated as a function of the frequencies by using an interference grid (to perform the optical equivalent of a fourier transform). The light is then focused onto a linear array sensor to collect the data.
There are all kinds of ways to simplify the technology and maybe improve it. For example, right now polarizers are used to eliminate non-coaxial light... that shouldn't be required. AND I really don't understand how OCT can be better than confocal microscopy[noparse]:)[/noparse]
