Phlox 40

WaveOptics’ Phlox is a transparent optical waveguide for full colour, near-eye augmented reality displays. Formed from glass with precision nano-structures, it is the key component used to overlay high resolution computer generated images over the real world.

A light engine generates images, which are coupled into a small input region. The light is transmitted along the Phlox waveguide (via total internal reflection) towards the output region where it is guided towards the eye.

2D pupil expansion, allows a small light engine to support a large eye-box. This enables an AR device that uses our waveguides to be small, light and it can accommodate different head sizes and eye separations.

WaveOptics Module Program

The WaveOptics Module Program gives customers early and easy access to waveguide and augmented reality (AR) technology.

Show mechanical properties

LCOS proto module also available

Customers are supplied with Phlox 40 waveguides and light engines, pre-aligned and mounted on a lightweight frame. Associated electronics are also provided.

The Module Program can be tailored to suit customers who are looking to:

  • Evaluate waveguides and waveguide development
  • Source AR modules for faster prototyping
  • Source AR modules for the production of AR products

Virtual Image

Image convergence and focal point are pre-aligned to a standard configuration. This can potentially be re-specified depending on the requirement and commercial model.

Image convergence at:

4m

Focal plane at:

Infinity

Large Eye-box

Allows no IPD adjustment and ease of viewing. If required this also allows a larger eye relief in a headset design.

Eye-box (at 25mm eye relief):

19 x 15mm

High-resolution Image

The WaveOptics module provides a high resolution display for each eye.

Display resolution:

1280 x 720

Wide Field of View

As standard left and right displays share 100% of the field of view. There is full overlap.

Diagonal field of view:

40°

High Optical Performance

System resolution supports HD display use.

Cycles/degree:

18 (at >=30%)

Outline Module Plans

Technical Specification

Binocular Components

2x Phlox waveguide assemblies. One left, one right.
2x WaveOptics light engines. One left, one right.
1x Chassis assembly connecting left to right.
1x Driver board / electronics.

Binocular Alignment

Supplied with the focal plane of the virtual image set to infinity.
Convergence between left and right eye will be set to 4 meters.

Monocular

Designed to enable use as a monocular module, details can be provided for specific applications.

Integration Options

Module can be integrated into new or existing systems by connecting directly to the light engine modules. WaveOptics can supply information necessary to facilitate this.

Large Eye-box

Allows a large variation in the viewing position without vignetting (cropping).

Tolerant of wide variations in human head/eye geometry.

Allows large eye relief and designs that can fit over conventional spectacles and does not require cumbersome “per-user” calibration.
