REAL IMAGE PROJECTION SYSTEM USING ASPHERIC ON-AXIS REFLECTOR |
| 摘要 |
A real image projection system comprising two or more optical surfaces of revolution (3, 4), with at least one comprising an aspheric surface of revolution for receiving images from a source (1). The aspheric surface of revolution is of a design to reduce natural aberrations inherent in imaging using surfaces of revolution of the conic family of curves.
