Waveguide‐Based Retinal Projection Near‐Eye Display with Bidirectional Eyebox Expansion

Advanced Intelligent Systems, EarlyView.
A waveguide‐type retinal projection display system with bidirectional extended eyebox is proposed. The two‐layer holographic optical elements (HOEs), with two eye reliefs of 11 and 12 mm in the axial direction, serve as the image combiner, and each layer of HOEs generates two viewpoints with a horizontal spacing of 5 mm. Based on the mechanism of human

Soft Robots Proprioception Through Stretchable Laser‐Induced Graphene Strain Sensors

Advanced Intelligent Systems, EarlyView.
This study demonstrates the potential of laser‐induced graphene and silicone sensors for soft pneumatic grippers’ proprioception. The sensors are thin, stretchable, mechanically transparent, and easy to integrate. Finite‐element method analysis identifies the finger's neutral bending plane and four sensor positions are tested to validate the ...

Design of Compact Liquid Crystal on Silicon Projection Optics Utilizing a Common Freeform Optical Path for Augmented Reality Displays

Advanced Intelligent Systems, EarlyView.
This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

A Field Programmable Gate Array‐Assisted Optoelectronic Emulator for Photonic Neuromorphic Computing

Advanced Intelligent Systems, EarlyView.
This work presents a hybrid optoelectronic architecture using field‐programmable‐gate‐array‐controlled optical components for multiplication operations. Data are encoded via electro‐optic modulator, weights are programmed via a variable optical attenuator, and results are detected by a photodetector.
