Compressed sensing for spectroscopy and polarimetry
Instituto de Astrofisica de Canarias
We demonstrate the feasibility of using compressive sensing techniques for the acquisition of spectroscopic and spectro-polarimetric data. This allows us to combine the measurement and the compression process into one consistent framework. Signals are recovered thanks to their compressibility, which will be analyzed in some detail. The results show that it is feasible to reconstruct the signals using only a small fraction of the information that is measured nowadays. This new paradigm allows us to define new instrumental strategies and to propose modifications to existing instruments in order to take advantage of compressive sensing techniques.
