1. A method of optimizing the scene presented to a viewer by a system employing a sensor including a wide angle optical system and a visual display comprising the steps of:
- arranging said sensor to have a field of view of a selected horizontal dimension; and
selecting a physical ratio for said display based on said horizontal dimension.

Abstract
Night vision apparatus including an infrared night vision sensor having a selected field of view and a display panel positioned for displaying an image detected by the sensor, the display panel having a display aspect ratio optimized based upon the horizontal dimension of the field of view of the infrared sensor such that the display aspect ratio decreases as the horizontal field of view narrows.

13. A method of determining optimum physical horizontal and vertical dimensions of a display for use with a vision system, the vision system including a sensor having a predetermined horizontal field of view, the method comprising the step of:
determining a ratio of a horizontal and a vertical dimension of said display based upon the predetermined horizontal field of view of the sensor, wherein the ratio is determined according to a relationship whereby the wider the predetermined horizontal field of view of the sensor, the narrower the display'"'"'s physical vertical dimension.
