Optical image projection device for use in helmet for projecting artificial image into eye of pilot, used in aeronautics field, has optical device for imaging rays striking surface of reflective mirror on surface of semi-reflective mirror

摘要

The device has a semi-reflective aspheric mirror (1.3) placed in a field of view of a user. A reflective aspheric mirror (1.5) is placed in axis of transmission of an image output from an imaging device, where usable surface of the reflective mirror is of form and size identical to usable surface of the semi-reflective mirror. The mirrors are placed in head-foot manner. An optical device (1.4) is placed between the mirrors and adapted to image a set of rays striking the surface of the reflective mirror on the surface of the semi-reflective mirror.
