نویسندگان

چکیده

By harnessing the properties of photonic quantum states and their interaction with environment, imaging promises to go beyond limits classical imaging. However, inherent weakness detected signals fragility make difficult measure in practice. In recent years, emergence single-photon sensitive cameras enabled field take a step closer practical applications. this respect, singlephoton avalanche diode (SPAD) are one most promising technologies as they can detect single photons across many pixels unparalleled speed, temporal resolution, very low noise.

Neural Imaging Using Single-Photon Avalanche Diodes

Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...

A 130nm CMOS Single Photon Avalanche Diode

We report on the first implementation of a single photon avalanche diode (SPAD) in 130nm CMOS technology. The SPAD is fabricated as p+/nwell junction with octagonal shape. A guard ring of p-well around the p+ anode is used to prevent premature discharge. To investigate the dynamics of the new device, both active and passive quenching methods have been used. Single photon detection is achieved b...

Photon-Efficient Computational Imaging with Single-Photon Avalanche Diode (SPAD) Arrays

Single-photon avalanche diodes (SPADs) are highly sensitive photodetectors that enable LIDAR imaging at extremely low photon flux levels. While conventional image formation methods require hundreds or thousands of photon detections per pixel to suppress noise, a recent computational approach achieves comparable results when forming reflectivity and depth images from on the order of 1 photon det...

Non-line-of-sight imaging using a time-gated single photon avalanche diode.

By using time-of-flight information encoded in multiply scattered light, it is possible to reconstruct images of objects hidden from the camera's direct line of sight. Here, we present a non-line-of-sight imaging system that uses a single-pixel, single-photon avalanche diode (SPAD) to collect time-of-flight information. Compared to earlier systems, this modification provides significant improve...

Single photon avalanche diode for single molecule detection

A commercially available single photon avalanche photodiode in a passively quenched circuit is used with time-correlated single photon counting modules to achieve subnanosecond time response together with high quantum efficiency and low dark noise. These characteristics are required for experiments in single molecule detection and spectroscopy in which time-gated detection schemes are used. By ...
