Distributed Compressed Sensing
Dror Baron等在其名为“Distributed Compressed Sensing”指出具有相关信息的多个观测源采用联合重构算法可以获取更好的重构效果，当观测源足够多时，甚至只需要K+1观测次数就可以完全重构出原信号。文献中提出了两种算法OSGA（One-Step Greedy Algorithm）和SOMP（Simultaneous Orthogonal Matching Pursuit）。

Fiber optic distributed sensing scheme for monitoring structural strain and deformation
&nbsp&nbsp
&nbsp&nbsp
&nbsp&nbsp
A　fiber　optic　distributed　sensing　scheme　used　to　monitor　structural　strain　and　deformation　is　presented.　In　the　sensor　system,　a　high-birefringent　optical　fiber　is　used　as　the　sensing　fiber,　and　the　sensor　units　along　the　sensing　fiber　distribution　are　arrayed　on　a　measured　test　structure.　The　structural　deformation　can　be　evaluated　by　detecting　the　polarization　mode　coupling　effect　in　each　sensor　unit　along　the　high-birefringent　fiber.　Interferometry　and　optical　path　scanning　are　used　to　determine　the　location　and　magnitude　of　the　mode-coupling　effects　caused　by　structural　strain　or　deformation.　(C)&#　Society　of　Photo-optical　Instrumentation　Engineers.
