    • 1l:\jzc\Interwovn\NRPortbl\DCC\JZC\14290194 _.docx-8 05/2017 Abstract A compensation lens, to be used for viewing an external world in series with the waveguide prism, which corrects for optical distortion caused by viewing the world through the waveguide prism; where the compensation lens comprises: i. a refractive outer surface, disposed towards an external scene, that allows light from the external scene to enter the compensation lens, ii. a refractive inner surface, disposed towards the outer surface of the waveguide prism, which allows light to exit the compensation lens and enter into the waveguide prism, where the refractive inner and outer surfaces of the compensation lens are designed to compensate for the effect of ray shift and distortion caused by the waveguide so that the user maintains a clear see-through view when observing the world through both lenses; where the refractive inner surface, may be constrained to approximate the shape of the outer surface of the waveguide prism, whereupon light from the real-world scene is refracted through the refractive outer surface and the refractive inner surface of compensation lens, before reaching the waveguide.

    • The present invention relates to a foveated imaging system capable of capturing a wide field of view image and a foveated image, where the foveated image is a controllable region of interest of the wide field of view image. The present invention also relates to a method of controlling a target region of a foveated image within a wide field of view image using a foveated imaging system.More specifically, the present invention concerns a dual-sensor wide-FOV foveated imaging technique which is capable of acquiring wide-FOV videos of a surrounding space in real time and simultaneously obtain very high resolution, high-magnification foveated images of multiple targets at high frame rate. The wide-FOV video, with appropriate resolution and frame rate, enables the real-time capability of simultaneously observing a surrounding space for acquiring, detecting, and tracking imminent threats posed by objects, while the high resolution foveated videos are focused on multiple small portions of the wide FOV in real time with substantially higher resolution to enable crucial target recognition and characterization. The region of interest (RoI) of the foveated view can be steered in real time to any part of the wide FOV image. These capabilities are analogous to the searching, tracking and foveation functions of the human visual system. By integrating the foveation capability into a wide-FOV imaging system, the present invention is able to capture a wide viewing field of up to 360° by 360° with high angular resolution. The present invention can be used in military and civilian surveillance applications.
