Overview - IEC TR 62629-41-1:2019 (Holographic display, general information)

IEC TR 62629-41-1:2019 is an IEC Technical Report that gathers technical information to support the standardization of holographic displays. It provides a general introduction to holographic display technologies, definitions (e.g., holographic display, complex amplitude, wavefront), and identifies the optical measurement items needed to characterize holographic 3D performance. The report is informative (no normative references) and complements other parts of the IEC 62629 series on 3D display devices.

Keywords: IEC TR 62629-41-1, holographic display, 3D display, spatial light modulator, optical measurement, wavefront.

Key topics and technical requirements

The report organizes technical content around technology, principles and measurable performance characteristics:

• Holographic display technologies and classification

  • Distinguishes holographic stereograms (piecewise wavefront continuity) from strict holographic displays (continuous wavefronts).
  • Covers SLM-based reconstruction techniques, including spatial and temporal multiplexing.

• Fundamental principles

  • Role of complex amplitude and wavefront reconstruction.
  • Encoding patterns for diffraction (interference patterns, phase encoding) rather than simple multi-view images.

• Performance characteristics to measure

  • Effective resolution items (space bandwidth product, three‑dimensional spot size, MTF).
  • Speckle and noise characterization and mitigation.
  • Distortion and chromatic aberration metrics.
  • Angular viewing direction range / viewing window and field-of-view (FOV) considerations.
  • Image volume, chromaticity, and luminance specifications.

• Measurement guidance

  • Informative Annex A covers measurement approaches for three-dimensional spot size, MTF, and colour gamut with illustrative figures and procedures.

Practical applications and who uses this standard

IEC TR 62629-41-1 is designed for stakeholders involved in research, development and pre‑commercial deployment of holographic 3D displays:

• Display engineers and optical system designers working on AR/VR eyewear, vehicle head-up displays (HUDs), and table-top holographic displays.
• Manufacturers of spatial light modulators (SLMs) and coherent light engines.
• Test labs, standards developers and QA teams defining measurement protocols for holographic displays.
• Research institutions and companies evaluating MTF, speckle behavior, viewing-window performance and color/luminance metrics.

Keywords: AR eyewear holographic display, HUD, SLM, MTF, speckle noise measurement.

Related standards

• The TR notes existing hologram standards (e.g., ISO 17901-1 / ISO 17901-2) focus on analogue static holograms and diffraction efficiency; they do not address the dynamic display aspects covered in IEC TR 62629-41-1.
• IEC 62629 series - this TR is one part of the broader 3D display device standardization work.
