High-dynamic-range imaging with photon-counting arrays (Conference Presentation)

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic

We present a comprehensive analysis to guide the use of the nonlinear photon response in photon-counting arrays to extend their optical dynamic range far beyond 1/Tdead, where Tdead is the pixel dead time after photon detection, so as to achieve a high dyn ...

A CMOS SPAD Imager with Collision Detection and 128 Dynamically Reallocating TDCs for Single-Photon Counting and 3D Time-of-Flight Imaging

Edoardo Charbon, Ivan Michel Antolovic, Chunmin Zhang, Scott Anthony Lindner, Martin Wolf

Per-pixel time-to-digital converter (TDC) architectures have been exploited by single-photon avalanche diode (SPAD) sensors to achieve high photon throughput, but at the expense of fill factor, pixel pitch and readout efficiency. In contrast, TDC sharing a ...

Dynamic range extension for photon counting arrays

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic

Confocal microscopes use photomultiplier tubes and hybrid detectors due to their large dynamic range, which typically exceeds the one of single-photon avalanche diodes (SPADs). The latter, due to their photon counting operation, are usually limited to an o ...

SPAD imagers for super resolution localization microscopy enable analysis of fast fluorophore blinking

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Samuel Burri

sCMOS imagers are currently utilized (replacing EMCCD imagers) to increase the acquisition speed in super resolution localization microscopy. Single-photon avalanche diode (SPAD) imagers feature frame rates per bit depth comparable to or higher than sCMOS ...
