Compressed sensing for spectroscopy and polarimetry

|
|
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.
