..... - it seems that we are both interested in the same thing, body scanning, with a double take - once with noise and once without, where the 2 takes are as close together in time as possible - is that right?
(My situation is, I've recently got into all this, I have just recently got about 12 various chdk cameras, so I just want to try some experiments with face scanning to start with.)
Re:- SYK-3 Sensor or similar Photoflash Slave devices for "...double take - once with (structured light) noise..."
Some time a go I had a part time job repairing Braun Flashes and also constructed quite a lot Photoflash Slave Triggers.
As this involves working with High Voltages I won't post any Details on the simple method's I used.
If you have only a Micro Budget you can re-purpose "Disposable (Single Use) Film Cameras" I just ask a local Film Processing Lab
to keep some for you, there are only a few brands and variations, and some are more useful than others.
There a lot's of ways the "Single Use Film Cameras" can be used as part of a DIY structured light projector array.
The main reason for using the "SU-FC" are the low cost and the "Synce'd" high intensity light pulsed output.
Some examples are (and for this post, the required modification details, are omitted):-
## With a obsolete 35mm Slide Projectors and/or just a "Triplett" (style) 35mm Slide Projection Lense.
## With a obsolete, back-lit, LCD Monitor using a "Triplett" 35mm Slide Projection Lense.
## With, a modified, "Cheap" Low Resolution LCD Digital Projectors, that are available on ebay etc.
## With, a modified, "Cheap" Low Resolution LCoS Digital Projectors, that are available on ebay etc.
## With, a modified, "Cheap" Low Resolution DLP Digital Projectors, that are available on ebay etc.
## With, a modified, "Expensive" High Resolution DLP Digital Projectors, that are available on ebay etc.
Note that you have two further structured light, Visible and Infrared projection options.
On the Camera array side I am experimenting with Visible and Infrared CHDK Cameras and a SDM style Mirror Box.
I.e. with an array of Visible and IR Stereo Camera (Photo-Scan camera) Pairs,
the advantage of the Vis-IR pairs are, that no delay's are required, so the camera array sync is excellent.

@ ottokar if you after more Legacy CHDK Cameras, I have some available; location Australia.
