MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202441035113 A) filed by Raman Research Institute, Banglore, Karnataka, on May 3, 2024, for 'an independently steerable double-trap optical tweezers with back-scattered confocal detection scheme.'
Inventor(s) include Ashraf, Md Arsalan; and Pullarkat, Pramod A.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses a system and method for dual optical trapping and position detection of particlesthat. The system uses back-scattered light for position detection using a pair of position detectors. The back-scattered detection of the two independently steerable traps requires optical design that combines the trapping optics as well as the optics for detection. The independently steerable dual optical trap is achieved using a confocal scheme which gives the advantage that the back-scattered light from the two independent traps remains centered on their respective detectors irrespective of the trap position. Such independently steerable double-trap optical tweezers is critical for the independent steering of the two traps without any need for changing the alignment of the detectors, avoiding cross-talk between detectors, and for convenient, single-module integration with high-end research microscopes."
