Multichannel freeform imaging optics: Applications to VR

Today’s manufacturing techniques allow not only using differentiable freeform surfaces but also surfaces with creases.

• Multichannelingis an optical design strategy that make use of these creases for splitting and stitching the bundles.

• This additional degree of freedom the design process allows:

• Imaging: increasing FOV
• Nonimaging: Increasing collection efficiency, controlling intensity and irradiance patterns
