ALEXANDRIA, Va., July 23 -- United States Patent no. 12,366,824, issued on July 22, was assigned to LAWRENCE LIVERMORE NATIONAL SECURITY LLC (Livermore, Calif.).
"Differential holography" was invented by Frank Ravizza (Brentwood, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Differential Holography technology measures the amplitude and/or phase of, e.g., an incident linearly polarized spatially coherent quasi-monochromatic optical field by optically computing the first derivative of the field and linearly mapping it to an irradiance signal detectable by an image sensor. This information recorded on the image sensor is then recovered by a simple algorithm. In some embodiments, an input field is split ...
