Method of horizontal widening of angular field of view of collimating optical system using several unified ax symmetric collimating optical systems spaced out horizontally with angular fields of view of rectangular shape with their boundaries oriented horizontally and vertically and their axes are turned horizontally relative to each other so that adjacent vertical boundaries of angular fields of view of neighboring systems coincide and full angular field of view of collimating optical system is sum of angular fields of view of unified optical systems included in it and to display total virtual information collimating optical system is conjugated with two-component combiner and primary image creators e.g. LCDs are located in focal planes of unified optical systems and wide-angle panoramic collimating optical system with horizontal field of view up to 360° can be build also.
