Abstract
An opto-mechanical deflector device is used for line displays and is worn by an observer. By use of the deflector device, the line presented by the line display on the observer's retina can be perceived as a two-dimensional image. The deflector device comprises, for each respective eye, a plurality of similar subsidiary deflectors which are spread out in a one-dimensional or two-dimensional matrix across a surface corresponding to the desired angle coverage for the respective eye. The subsidiary deflectors are provided in such a number that the lines which the line display presents can be seen unbroken, irrespective of the line of sight of the eye within the field of view of the deflector device.
