Depth and Transient Imaging with Compressive SPAD Array Cameras [PDF]
2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition, 2018 Time-of-flight depth imaging and transient imaging are two imaging modalities that have recently received a lot of interest. Despite much research, existing hardware systems are limited either in terms of temporal resolution or are prohibitively expensive.

A flexible compact readout circuit for SPAD arrays [PDF]
SPIE Proceedings, 2010 A compact readout circuit that can be integrated between individual single photon avalanche detectors (SPADs) is described. The circuit uses minimum sized transistors to both quench the avalanche process in the photodetector and integrate charge onto a capacitor to represent the number of detected photons.

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.Shewanella oneidensis and Bacillus subtilis, both harboring prophages, reveal a novel biosynthetic route to scalable and programmable DNA superstructures in flower‐ and wire‐like shapes, respectively. Activation of prophages is achieved via 3‐hour starvation and monitored using reporter strains.
