Embedded relay lens for head-up displays or the like |
摘要 |
Briefly, in accordance with one or more embodiments, an optical relay comprises a partially-reflective-coated Fresnel lens or similar low-profile lens such as a diffractive lens or a holographic lens having a first index of refraction and a filler medium having a second index of refraction and being disposed adjacent to the Fresnel lens. The optical relay enables the optical power of the Fresnel or similar low-profile lens embedded within the two layers to influence a beam that is reflected from the optical relay while allowing transmitted light to experience little or no influence from the embedded lens.
