IntelligentQuantum Imaging(IQI) Lab

Physics-aware imaging beyond the direct line of sight.

We develop single-photon systems, neural light transport, and computational imaging methods to reveal what light almost hides.

Research Publications
01

Photon Measurement

Single-photon detection, time-resolved acquisition, and adaptive measurement for sparse light.

02

Neural Reconstruction

Physics-informed neural fields and learning systems for complex light transport and scene recovery.

03

Imaging Systems

End-to-end imaging pipelines and hardware systems for real-world deployment.

02 / Research

Light transport as signal, geometry, and computation.

IQI connects photon-efficient measurement with physics-aware reconstruction. The work spans instruments, inverse models, neural representations, and deployable imaging systems.

01
Top-view non-line-of-sight imaging setup with laser and relay wall.

Photon Measurement

Time-resolved sensing, single-photon acquisition, sparse scanning, calibration, and measurement design for scenes where photons are scarce or delayed.

02
Neural Transient Fields pipeline diagram.

Neural Reconstruction

Physics-aware neural fields, transient transformers, masked pretraining, and inverse rendering methods that convert sparse measurements into geometry and transport.

03

Imaging Systems

End-to-end computational imaging pipelines for NLOS recovery, plenoptic time-of-flight, scattering media, and real-world deployable hardware.

NLOS imaging setup and reconstruction comparison.
Transient reconstruction Learnable inverse kernels and attention mechanisms recover high-frequency structure from time-resolved measurements.
