Splet16. dec. 2014 · Compressed sensing (CS) is a relatively new technique in the signal processing field which allows acquiring signals while taking few samples. It works for sparse signals and has a few restrictions which we will get into. For those familiar with the Nyquist rate, it states that in order to obtain all relevant information in a signal, the ... Splet13. sep. 2007 · In contrast, the wavefront sampling of a PD sensor is based on the size of its processed images. This says that if a system requires low-order modes corrected more frequently, then smaller images are sufficient much of the time. This enabling feature allows even more speed since smaller image chips are read out and processed faster.
