Applications of Holographic Lenses in Head Up Displays
Abstract
This article does research on the formulation of images and aberration characteristics associated with holographic lenses, and brings out the design principles, design programs, and actual examples for holographic head up display devices. Head up displays are one type of advanced observation and aiming instrument which is used in modern aircraft--in particular, in fighter planes. They are capable of supplying to flight personnel a wealth of flight information, and they have great significance for lightening the observation burden of flight personnel and raising the combat characteristics of the aircraft. As far as the important sections in the optical systems of head up displays are concerned, although they normally possess the strong points of familiarity of the industrial techniques in their manufacture, and their simplicity and ease of structural installation; however, due to such weak points as small field of vision and the contradiction between high transparency and high reflection, very great limitations have been placed on the exerting of the capabilities of head up displays devices. However, holographic lenses are still capable of very satisfactorily resolving these two problems. Because of this, one has seen the appearance of taking holographic lenses and replacing the holograph type optical systems of composite devices.
