National Central University, Taoyuan, Taiwan, has been assigned a patent (11,100,950) developed by Yu, Yeh-Wei, and Sun, Ching-Cherng, Taoyuan, Taiwan, for “method for reading and writing with holographic system and holographic storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method for reading and writing with holographic system includes the following operations: (a) providing a reference light and a signal light; (b) transferring the reference light and the signal light to an optical recording medium, for recording an interference grating; (c) changing the reference light and the signal light and repeating the operations (a) to (b) until M interference gratings are recorded on the optical recording medium; (d) providing a reading light to the optical recording medium, for reading the M interference gratings at the same time to generate an interference result, wherein the interference result is a result that diffraction signals of the M interference gratings interfere to each other; and (e) changing the reading light and repeating the operation (d), for obtaining N interference results. A holographic storage system is also disclosed herein.”

The patent application was filed on October 29, 2020 (17/084,607).
