MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641063310 A) filed by P Venkata Krishna; and Bhavani Kumar Yellapragada, Tirupati, Andhra Pradesh, on May 19, for 'polarization-diverse swept-source optical coherence tomography system with active polarization modulation and hybrid ai-accelerated processing.'
Inventor(s) include Sandhya Tatekalva; P Venkata Krishna; Bhavani Kumar Yellapragada; and G. Prathyusha.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "A polarization-diverse swept-source optical coherence tomography (SS-OCT) system with active upstream polarization modulation, multi-channel polarization-diverse detection, and a hybrid FPGA/GPU-AI processing pipeline is disclosed. The system dynamically modulates polarization states synchronized with wavelength sweeps, captures full orthogonal polarization information to minimize artifacts, and delivers real-time or near-real-time structural and functional imaging (birefringence, retardation, depolarization, optic axis orientation) at A-scan rates 100 kHz (preferably 400 kHz). The synergistic integration overcomes polarization-dependent signal fading and latency limitations of prior art, enabling robust clinical applications in ophthalmology, cardiology, dermatology, and endoscopy."
