ABSTRACT:
Non-distorting mirrors are disclosed that are each curved in at least one plane and positioned relative to an observer in accordance with a mathematical relation by which the observer is presented with a virtual image of a selected field of view of the surroundings, the virtual image having a specified angular magnification or demagnification without angular distortion in the aforementioned plane. Such a mirror may be designed to have a value of angular demagnification for which a wide field of view of the surroundings is compressed within the narrower angular limits of the mirror relative to the observer and may be employed as a rear- or side-view mirror for an automobile, aircraft, or other vehicle. This mirror may be employed in addition to or in combination with a conventional plane rear- or side-view mirror.
