Speckle spectroscopy with tip-tilt operation.
A stellar speckle spectrometer with tip-tilt operation is proposed for high-spatial-resolution spectroscopy under atmospheric turbulence. A specklegram is used to drive a tip-tilt mirror for real-time shift-and-add operation to its dispersed specklegram. The proposed speckle spectroscopy attains a long exposure for the spectrum and a slit spectrometer. Several simulation experiments confirm the effectiveness of our method.
