Abstract : This patent relates to usual projection systems and particularly to usual projection systems for use as training simulators. A field of view test apparatus utilizes a plurality of interchangeable acrylic masks to vary the resolution characteristics of a projected field of view. An eye or head tracker provides line of sight direction signals to a servo which positions the mask with the optical path of the projection to correlate the area of higher resolution with the direction of the line of sight.
