ABSTRACT
The emerging field of compressive sampling has some potentially powerful implications for the design of optical systems. The mathematics of compressive sampling (CS) suggests that one can recover data at a higher spatial or temporal resolution than is implied by the resolution of the recording device. As research in the field has progressed, and CS devices are built and tested, issues related to practical implementation have become the important topics in the field. In this entry, we provide an overview of the field from an optics perspective, covering the basic theory and background, and then focus on two possible CS system architectures. In the first, we describe a CS-infrared imager and present a numerical exploration of this system. We then describe a CS photonic link and present experimental results demonstrating its performance.
