Patent ID: 11510586

Abstract:
A novel method and system for enhanced-resolution THz imaging whereby an enhanced-resolution THz image is developed by deconvolution of the original THz image that is developed using THz signals that are manipulated in time-domain and/or in frequency-domain and a point spread function (PSF) that is developed according to an equation wherein said THz signals in time-domain and/or frequency-domain are input parameters. By using this method and system, enhanced-resolution THz images are developed for detecting traces of symptoms of COVID-19 as small as a drop of water. Said novel method and system for enhanced-resolution THz imaging is used for developing a device, and method, that is: (a) rapid, (b) economical, (c) able to perform measurements remotely, (d) non-invasive. This device, and method, is capable of detecting symptoms of COVID-19 such as runny nose, congestion, and cough. The person under examination may or may not wear a face covering mask. This device, and method, is capable of performing examination remotely and without needing the person to remove the mask.
