Latest Patents
Among his latest inventions is a helmet-mounted display system designed to combine a display image with the viewer's field of view. This apparatus utilizes light from either a night vision system or a CRT, directing it into an eyepiece assembly that magnifies and focuses the image into a combiner. The combiner consists of an elongated optical element with two parallel sides and two concave reflective surfaces at each end. The light is reflected off the first reflective surface and bounces back and forth between the sides of the combiner before reaching the second reflective surface. This innovative design allows the display image to be superimposed in the viewer's field of view while maintaining a lightweight structure that minimizes distortion and offers a wide field of view.
Another notable patent is the helmet-mounted display with improved brightness. This invention features a filter that receives rays of light at various angles from an image to be superimposed on the scene viewed by the operator. The filter reflects these rays to a second surface, where they are re-reflected through the filter to the observer's eye. The unique coating on the filter allows it to reflect rays from the image at predetermined angles while transmitting rays received from the second surface.
