US Patent Issued to Lawrence Livermore National Security on Nov. 25 for "Spectrograph stabilization using a single-delay interferometer" (California Inventor)

ALEXANDRIA, Va., Nov. 25 -- United States Patent no. 12,480,815, issued on Nov. 25, was assigned to Lawrence Livermore National Security LLC (Livermore, Calif.).

"Spectrograph stabilization using a single-delay interferometer" was invented by David J. Erskine (Oakland, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods, systems and devices are described that improve optical spectroscopic techniques and particularly those that involve externally dispersed interferometer (EDI) techniques that result in an output spectrum having improved stability characteristics. The output spectrum minimizes the unwanted shifts in wavelength when the spectrograph component of the EDI instrument is under stresses th...
