Effect of the Pixel Photosensor Width on the Recovered Spectral Intensity in Interferometric Imagers and the Correction

Abstract:

The equation for the recovered spectrum is derived in spatially modulated interferometric imagers, which takes into account the pixel photosensor width. The results show that the effect of the pixel photosensor width on the recovered spectral intensity is related to the wavenumber and the intensity of the incident spectrum, which causes the broadband spectral waveform changed, and the distortion increases with the spectral bandwidth increasing. A mathematical algorithm is given to correct the distortion, and the experimental results show this method is effective.
