Abstract

Projected specklegrams are used for spectroscopy with high spatial resolution under atmospheric turbulence. One-dimensional peak tracking allows one to realize high throughput and simple real-time operation for speckle spectroscopy. Results of simulation experiments are presented, and they confirm the usefulness of the proposed method.
