Increase of Charge-Coupled Device Resolution limits using Spatial Light Modulator

Mohammad Sohail, Nigar Fida, Haroon Khan, Muhammad Noman Hayat

Abstract


Resolution of the imaging devices is mainly restricted by the pixels pitch, the pixels size and shape. We show a methodology where a Liquid Crystal on Silicon presentation is utilized to produce diverse direct stages at the article phantom plane, prompting distinctive sub-pixel relocations of the item picture at the picture plane. Along these lines, pictures of the same item with various movements are inspected by Charge-Coupled Device (CCD) camera. At long last, all the acquired pictures are legitimately consolidated prompting a last super-determined picture. Correlation of unique article and the one acquired with our methodology plainly affirm a noteworthy change in determination.
