Holographic diffraction-through-aperture spectrum splitting system and method

A diffraction-through-aperture spectrum splitting apparatus for obtaining energy from a polychromatic energy source that emits radiation in a first and a second wavelength band, comprising:

• a first energy receiver having an open aperture therethrough, the first energy receiver suitable for converting or storing energy from radiation within the first wavelength band;
• and
• a holographic lens configured to split the first and the second wavelength bands such that it diffracts and focuses the radiation within the second wavelength band from the energy source through and beyond the open aperture for capture beyond the open aperture by a second energy receiver positioned beyond the open aperture, and transmits the radiation within the first wavelength band from the energy source to the first energy receiver, wherein the open aperture is positioned between the first and the second energy receivers, wherein the first energy receiver includes photovoltaic cells or a thermal receiver, and the second energy receiver includes photosensitive plants or algae.

A diffraction-through-aperture spectrum splitting method for obtaining energy from a polychromatic energy source that emits radiation in a first and a second wavelength band, employing a reflector or a first energy receiver, in each case having an open aperture therethrough, comprising:

• diffracting and focusing, using a holographic lens configured to split the first and the second wavelength bands, the radiation within the second wavelength band from the energy source through and beyond the open aperture for capture beyond the open aperture by a second energy receiver positioned beyond the reflector open aperture or beyond the first energy receiver open aperture, wherein the second energy receiver includes photosensitive plants or algae;
• and
• transmitting the radiation within the first wavelength band through the holographic lens from the energy source to the first energy receiver or to the reflector, in each case wherein the open aperture is positioned between the first and the second energy receivers, or wherein the open aperture is positioned between the reflector and the second energy receiver.
