MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641047801 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 15, for 'continuous liquid crystal phase modulation membrane for holographic wavefront synthesis.'
Inventor(s) include Bapatla Surendra Babu; and Irukumalli Priyanka.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to MOEMS and holographic displays. A technical problem with current displays is their reliance on discrete pixelated matrices, which inherently introduce phase quantization errors and fail to accurately synthesize continuous three-dimensional light fields. The solution is an analog continuous-phase holographic wavefront synthesis architecture. The apparatus comprises a continuous nematic liquid crystal layer (140) sandwiched between unsegmented resistive analog electrodes (130). By driving voltages strictly at perimeter boundary contacts (150), a smooth voltage gradient (210) forms via Ohmic conduction without discrete electrode segmentation. This induces a continuous molecular director reorientation (220). Illuminated by a coherent laser backlight (110), the membrane accumulates a spatially continuous optical phase delay. A resulting continuous analog wavefront (240) synthesizes a three-dimensional hologram bounded primarily by a continuous diffraction limit (340), physically matching the continuous natural light fields expected by human vision. The principal use is high-fidelity extended reality displays."
