Non-contact lens metrology from optical flow and differentiable ray tracing
Hector A. Jimenez-Romero, Wolfgang Heidrich
Accurate lens surface metrology is essential to determine the manufactured geometry of refractive optical elements and their deviation from the specified design. We demonstrate a t…
High-capacity computing with self-rectification nonlinear optical neural processor
Ruicheng Ma, Siyu Dong, Yuzhi Shi +14
Artificial intelligence (AI) and neural networks have driven groundbreaking innovations across numerous disciplines. Optical computing offers the promise of unprecedented speed and…
Disparity Has a Sign: Stereo Matching Beyond the Zero-Disparity Plane
Jian Shi, Xinge Yang, Chaoyang Wang +2
Modern stereo matching models fail when disparity crosses zero, with end-point error (EPE) rising by 4.6-37. Yet stereoscopic content, from cinema 3D to VR, routinely conta…
Low Latency Gaze Tracking via Latent Optical Sensing
Yidan Zheng, Matheus Souza, Kaizhang Kang +3
We present a real-time gaze tracking system that directly acquires task-relevant latent features using a fully passive optical encoder. Instead of forming and processing full-resol…
End-to-end differentiable design of geometric waveguide displays
Xinge Yang, Zhaocheng Liu, Zhaoyu Nie +4
Geometric waveguides are a promising architecture for optical see-through augmented reality displays, but their performance is severely bottlenecked by the difficulty of jointly op…
Learned Off-aperture Encoding for Wide Field-of-view RGBD Imaging
Haoyu Wei, Xin Liu, Yuhui Liu +4
End-to-end (E2E) designed imaging systems integrate coded optical designs with decoding algorithms to enhance imaging fidelity for diverse visual tasks. However, existing E2E desig…
Collaborative On-Sensor Array Cameras
Jipeng Sun, Kaixuan Wei, Thomas Eboli +6
Modern nanofabrication techniques have enabled us to manipulate the wavefront of light with sub-wavelength-scale structures, offering the potential to replace bulky refractive surf…
Large-Area Fabrication-Aware Computational Diffractive Optics
Kaixuan Wei, Hector A. Jimenez-Romero, Hadi Amata +4
Differentiable optics, as an emerging paradigm that jointly optimizes optics and (optional) image processing algorithms, has made innovative optical designs possible across a broad…
Latent Space Imaging
Matheus Souza, Yidan Zheng, Kaizhang Kang +3
Digital imaging systems have traditionally relied on brute-force measurement and processing of pixels arranged on regular grids. In contrast, the human visual system performs signi…
End-to-End Hybrid Refractive-Diffractive Lens Design with Differentiable Ray-Wave Model
Xinge Yang, Matheus Souza, Kunyi Wang +3
Hybrid refractive-diffractive lenses combine the light efficiency of refractive lenses with the information encoding power of diffractive optical elements (DOE), showing great pote…
MetaISP -- Exploiting Global Scene Structure for Accurate Multi-Device Color Rendition
Matheus Souza, Wolfgang Heidrich
Image signal processors (ISPs) are historically grown legacy software systems for reconstructing color images from noisy raw sensor measurements. Each smartphone manufacturer has d…
Limitations of Data-Driven Spectral Reconstruction -- An Optics-Aware Analysis
Qiang Fu, Matheus Souza, Eunsue Choi +3
Hyperspectral imaging empowers machine vision systems with the distinct capability of identifying materials through recording their spectral signatures. Recent efforts in data-driv…
