Supplemental content for "An inexpensive programmable illumination microscope with active feedback" by Nathan Tompkins and Seth Fraden. Supplemental Animation.mov - An animation further demonstrating the software flow of the active feedback software for the programmable illumination microscope. Supplemental Software.zip - Matlab code to assist in the setup of the active feedback software and alignment of a programmable illumination microscope. Includes dependencies and sample output. Supplemental Video 1 200x.mov - Data from a close packed water-in-oil emulsion of chemical oscillators demonstrating the object tracking capabilities of the active feedback software for the programmable illumination microscope. The movie shows a wide field of view and is presented at 200x real time. Supplemental Video 1 and 2 are of the same data, only the field of view is different. Supplemental Video 2 200x.mov - Data from a close packed water-in-oil emulsion of chemical oscillators demonstrating the object tracking capabilities of the active feedback software for the programmable illumination microscope. The movie shows a small portion of the field of view and is presented at 200x real time. Supplemental Video 1 and 2 are of the same data, only the field of view is different.
