Query: Spatio-temporal Compressed Sensing with Coded Apertures and Keyed
  Exposures   Optical systems which measure independent random projections of a scene
according to compressed sensing (CS) theory face a myriad of practical
challenges related to the size of the physical platform, photon efficiency, the
need for high temporal resolution, and fast reconstruction in video settings.
This paper describes a coded aperture and keyed exposure approach to
compressive measurement in optical systems. The proposed projections satisfy
the Restricted Isometry Property for sufficiently sparse scenes, and hence are
compatible with theoretical guarantees on the video reconstruction quality.
These concepts can be implemented in both space and time via either amplitude
modulation or phase shifting, and this paper describes the relative merits of
the two approaches in terms of theoretical performance, noise and hardware
considerations, and experimental results. Fast numerical algorithms which
account for the nonnegativity of the projections and temporal correlations in a
video sequence are developed and applied to microscopy and short-wave infrared
data.
