Spectral imaging has been used in a variety of fields. Recently, scattering media have been employed in spectral imaging for spectrally-dependent random modulations. This approach has realized single-shot and compact hardware spectral imagers. One drawback of such spectral imaging is a careful calibration process to know the scattering process for the reconstruction. In the field of imaging through scattering media, speckle correlation is known as a technique for imaging through unknown media by utilizing a shift-invariance of speckle, called the memory effect. In this study, we present single-shot spectral imaging based on speckle correlation without the need for calibration.
