 **Ultra-thin (2.5 mm) glasses-form factor VR display supporting 3D holographic images**

We present Holographic Glasses, a holographic near-eye display system with an eyeglasses-like form factor for virtual reality. Holographic Glasses are composed of a pupil-replicating waveguide, a spatial light modulator, and a geometric phase lens to create holographic images in a lightweight and thin form factor. The proposed design can deliver full-color 3D holographic images using an optical stack of 2.5 mm thickness. A novel Pupil-high-order gradient descent algorithm is presented for the correct phase calculation with the user’s varying pupil size. We implement benchtop and wearable prototypes for testing. Our binocular wearable prototype provides a diagonal field of view of 22.8°, a 2.3 mm static and 8 mm dynamic eye box, and it supports 3D focus cues, weighing only 60 𝑔, excluding the driving board.
