CS: A Cheap Structured Illumination Capability for Compressive Imaging

If you recall the reason one could not do a single pixel camera was because of cost for the DMD and a driver of the TI DMD. It looks like this situation is over. You can now buy a TI DLP and a board that drives it for less than $500.

Of interest in the recent DLP Pico projector version 2 are the following new features (my emphasis):

# Direct Connection to a PC *New*

* Connects to a DVI port for out-of-box operation

# Sync Signal Output *New*

* Connects to a sensor (e.g. camera) to enable structured lighting applications

# Selectable DMD Pattern Timing *New*

* Enables 50Hz, 60Hz video frame rates & 120Hz, 180Hz, 240Hz, 480Hz, 1200Hz, 1440Hz, 2400Hz DMD pattern rates

While one can use this hardware for making a single pixel camera, one can also use as a way to perform calibration. Here are some videos on how it is to use it out of the box with the BeagleBoard (the Pico BeagleBoard site is here)
