High-end optical metrology tools for challenging optical systems

Augmented Reality and Virtual Reality - high end optical metrology tools | Phasics

Future products for augmented reality (AR), mixed reality (MR) and virtual reality (VR) will be more compact and will exhibit unprecedented image quality. To lead to such products, a lot of development is performed on integrated photonics, materials, projection, and display. In all these areas the Phasics SID4 wavefront sensors can solve metrology challenges.

Shrinking the size of headsets is one of the main challenges of the AR/VR market. Metasurfaces and metaoptics represent a promising approach. Optical functions and designs for metaoptics can be qualified and controlled using Phasics' technology.

Component measurements

In order to reach high image-quality requirements, every component of the headset has to be carefully designed, manufactured, and qualified. Phasics' metrology test stations are used for quality control at the component and assembly levels.

Alignment and system testing

Once the optical components are mounted together and aligned, the subsystems are tested for wavefront error (WFE) and modulation transfer function (MTF). Phasics proposes optical test stations and custom optical test benches for performing such measurements.
