Latest Patents
Zuojin Sha holds a patent for an "Only-readable three-dimensional optical storage device." This invention relates to information storage and comprises several components, including a computer, a precise rotary table, a writing laser source, a readout laser source, a spatial filter, a spatial light modulator, lenses, mirrors, photorefractive crystals (such as doubly doped lithium niobate), and a phase-mismatch adjustor. By utilizing green light (532 nm) for writing and red light (670 nm) for reading, the invention significantly improves the signal-to-noise ratio and addresses the challenge of fixing stored information. The transmission configuration enables high-density digital storage, with an irregular lens designed to function as a phase-mismatch adjustor, allowing for the retrieval of the entire stored image without distortion or loss. The dynamically differential encoding and decoding technique employed in this invention suppresses the bit-error rate to below 10.
