Simulative study on speckle – spectral properties of a random pixelated grating

Speckle spectrometers based on disordered media have shown great prospects and attracted more and more attention. To obtain a larger bandwidth and higher light-energy utilization ratio, a novel speckle spectrometer scheme is proposed based on a random pixelated grating. The speckle generation ...
