This work proposes a continuous compressive image acquisition system utilizing coded exposure with simultaneous exposure with simultaneous exposure and readout control that achieves both flexible spatial and temporal resolution while maintaining continuous video capability.
High-speed three-dimensional imaging is essential for the quantitative analysis of rapidly evolving dynamic phenomena such as combustion, fluid flow, and biological motion. However, conventional approaches suffer from the bulky form factor of multi-camera systems, limited frame rates, or a reliance on active illuminati...

Single-pixel cameras (SPCs) offer a compact and cost-effective imaging solution for spectral ranges where conventional sensor arrays are costly or impractical. However, long reconstruction times and the lack of intermediate visual feedback significantly limit their applicability in real-time scenarios. In this work, we...

Conventional frame-based Shack--Hartmann wavefront sensors (SHWFS) are limited by dynamic range and the intrinsic trade-off between spatial and temporal resolution, while high-bandwidth acquisition poses additional challenges for real-time wavefront reconstruction. This work presents a real-time, megapixel, kilohertz n...
A novel tone mapping method that not only bridges the gap between HDR RAW inputs and the LDR sRGB requirements of detection networks but also achieves end-to-end optimization with downstream tasks and achieves real-time processing of 4K high-bit-depth HDR inputs on NVIDIA Jetson platforms.

Terahertz near-field imaging enables high-resolution biomedical and material characterization by combining the non-ionizing nature of terahertz radiation with sub-wavelength spatial resolution. However, the scalability of existing solid-state near-field imagers is fundamentally limited by shared illumination scheme...
