Latest Patents

Gaurav Dwivedi holds a patent for a "Method and system for recording digital holograms of larger objects in non-laboratory environment." This invention optimally produces holographic images using a Holographic Optical Element (HOE). The HOE is designed to control the directions and divergences of light beams, which contributes to the compactness of the system. The system employs concave and convex lenses along with other optical components to achieve high throughput and compact design. A neutral density filter is utilized to adjust the intensity of the reference beam, ensuring that it matches the intensity of the object beam for high-quality digital holograms. The design minimizes the effects of vibrations through anti-vibration mounts and a rigid platform, while an electro-optical sensor array records holograms digitally. An algorithm is then used to numerically reconstruct and quantify the results on various devices.
