Remember when a year and a half ago, I mentioned that the 'thing' that enables one to render compressive measurement universal and timeless should not be called a light modulating device or a rotating collection of masks, but rather a Randomized Carousel.

Well, it looks like we have an instance of one: Spinning disk for compressive imaging by H. Shen, L. Gan, N. Newman, Y. Dong, C. Li, Y. Huang, and Y. C. Shen. The abstract reads:
We report the first, to the best of our knowledge, experimental implementation of a spinning-disk configuration for high-speed compressive image acquisition. A single rotating mask (i.e., the spinning disk) with random binary patterns was utilized to spatially modulate a collimated terahertz (THz) or IR beam. After propagating through the sample, the THz or IR beam was measured using a single detector, and THz and IR images were subsequently reconstructed using compressive sensing. We demonstrate that a 32-by-32 pixel image could be obtained from 160 to 240 measurements in both the IR and THz ranges. This spinning-disk configuration allows the use of an electric motor to rotate the spinning disk, thus enabling the experiment to be performed automatically and continuously. This, together with its compact design and computational efficiency, makes it promising for real-time imaging applications
While the paper is behind a paywall, here are the videos showing some results of reconstruction using:
This will be added to compressive sensing hardware shortly.
