Abstract:

A high-resolution vision system comprising remotely positioned image-sensing means, such as a TV camera, and a head-mounted display that is used by an observer to view the image picked up by the remote sensors. Both the sensing means and the display are servo controlled to follow the eye line-of-sight (LOS) of the observer. The eye LOS is characterized by the eye angle of the observer with respect to his head plus the head angle with respect to a reference axis, such as the center line of an aircraft. Because the display follows eye motion by means of a servoed mirror or beamsplitter in front of the eye, the eye always looks at a fixed point on the display. The resolution of the display preferably is increased on the LOS so that the display characteristics closely match the eye, i. e. , high resolution on the eye LOS and lower resolution in the peripheral region. This preferably is accomplished by using dual sensing means, such as dual TV cameras, one with a wide and the other with a narrow field of view.
