Hardware implementations of computer-generated holography: a review

Abstract

Computer-generated holography (CGH) is a technique to generate holographic interference patterns. One of the major issues related to computer hologram generation is the massive computational power required. Hardware accelerators are used to accelerate this process. Previous publications targeting hardware platforms lack performance comparisons between different architectures and do not provide enough information for the evaluation of the suitability of recent hardware platforms for CGH algorithms. We aim to address these limitations and present a comprehensive review of CGH-related hardware implementations.

HoloBlade: an open-hardware spatial light modulator driver platform for holographic displays

“…This scalability is important for HoloBlade to see significant uptake. Moreover, using a FPGA allows dedicated CGH hardware accelerators to be implemented directly in the FPGA fabric, supporting the current trends within the field [19]; performing the complex CGH routines in dedicated hardware increases performance and reduces the software complexity for researchers.…”

Automotive Augmented Reality: User Experience and Enabling Technology

“…In traditional static holography, the amplitude and phase of the light reflecting from an object are recorded into a photosensitive material (e.g., dichromated gelatin) by interfering the object beam with the reference beam ( Fig . ) 6 . The photosensitive material with the recorded interference pattern is referred to as a hologram.…”

“…4a). 6 The photosensitive material with the recorded interference pattern is referred to as a hologram. For reconstruction of the object beam, a coherent beam having the same wavelength as the reference beam is used to illuminate the hologram from the same direction as the recording reference beam.…”

“…Northwestern Universitybased research performed in a full vehicle driving simulator demonstrated a 30 percent improvement in eyes-on-road time with the addition of surface haptics. 6 Designers also should seek to minimize the number of menus needed to access controls, as this contributes to cognitive load.…”
