The range to an object is obtained by conveying light rays from the object through an afocal telescope to spatially displaced objective lenses that view the scene from two displaced points of view. The scene images from the objective lenses are focussed on two television sensors, respectively. The video frame from the TV sensors are digitized and stored in respective frame grabbers. A timing and logic circuit controls the television sensors and frame grabbers to alternately provide frames from the two television sensors to a monitor. The timing and logic...
Range finding apparatus for passively finding the range to an object, comprising: afocal lens means for conveying light rays from said object, first and second spatially displaced television sensor channels positioned to receive light rays conveyed by said afocal lens means for providing first and second video signals representative of spatially displaced images of said object, respectively, shifting means for time shifting said second video signal with respect to said first video signal, and means coupled to said shifting means and to said first and sec...
