摘要： A holographic display (“display”) for a head-mounted display (“HMD”). The display includes a source configured to emit at least partially coherent light and a beam conditioner that conditions the light from the source into one or more beams of light. The display also includes one or more spatial light modulators configured to encode the one or more beams of light using a hologram of a virtual reality image. The display further includes an objective lens and a conversion lens. The objective lens is positioned to create an intermediate image at a Fourier plane, and the intermediate image is a Fourier transform of the hologram. The conversion lens performs a Fourier transform of the intermediate image to generate an output hologram. The conversion lens also magnifies a portion of the output hologram and directs the magnified portion of the output hologram to an exit pupil of the HMD.
