Abstract
A holographic telescope ( ). The novel invention is comprised of an eyepiece ( ) and a first holographic optical element ( ) positioned to receive incident electromagnetic energy and focus the energy on the eyepiece ( ). In the preferred embodiment, the eyepiece ( ) is a second holographic optical element, and both holographic optical elements are volume holograms. Each holographic optical element can be transmissive or reflective depending on packaging needs. The holographic telescope ( ) can be multi-spectral by including multiple independent holograms in each holographic optical element, each hologram responding only to a particular wavelength.
