Compressed sensing is an innovative signal processing paradigm that enables the reconstruction of signals from a limited number of measurements, provided that the signal is sparse or compressible ...

Compressed Sensing: A signal processing technique that recovers sparse signals from far fewer measurements than traditionally required, typically through optimised reconstruction algorithms.

Coded aperture compressive imaging is described for two important imaging modalities: Spectral and Tomographic Imaging. Both capture 3D data cubes with just a few 2D detector array measurements.
