Dynamically Adjustable LiDAR with SPAD Array and Scanner

SAE Technical Paper Series, 2021
<div class="section abstract"><div class="htmlview paragraph">An important function of an Automated Driving (AD) system is to detect objects including vehicles and pedestrians on the road. Typical devices for detecting those objects include cameras, millimeter-wave RADAR, and light detection and ranging (LiDAR).

Quantum imaging with SPAD arrays (Conference Presentation)

Single Molecule Spectroscopy and Superresolution Imaging XIII, 2020
The emerging field of quantum imaging introduces new methods to overcome classical limitations in optical microscopy. A detection apparatus capable of analyzing the quantum signature of light, is a crucial component in the heart of any such method. We present a novel quantum imaging modality, based on a state-of-the-art single photon avalanche diode (

Reconfigurable coaxial single-photon LIDAR based on the SPAD array

Applied Optics, 2023
The single-photon avalanche diode (SPAD) array with time-to-digital converter (TDC) circuits on each pixel is an excellent candidate detector for imaging LIDAR systems. However, the low fill-factor of the SPAD array does not allow for efficient use of laser energy when directly adopted in a LIDAR system.

Compact CMOS Analog Counter for SPAD Pixel Arrays

IEEE Transactions on Circuits and Systems II: Express Briefs, 2014
In this brief, the design and experimental characterization of a compact analog readout circuit for photon counting is presented. A test chip, including a 20 × 20 counter array, has been manufactured in a standard 0.35-μm CMOS technology. The circuit delivers an output voltage proportional to the input pulse count, with a programmable voltage step. The

Preliminary Test Measurements of the SPAD Array

2004
This is a progress report on preliminary test measurements aimed to evaluate the performance of new Single Photon Avalanche Diodes (SPAD) developed by ST Microelectronics. Various samples with different dimensions (from 10 to 100 μm diameter) and two 5x5 arrays (20 and 40 μm) are manufactured by STM; some of which have been characterized.

SPAD arrays for parallel photon counting and timing

2010 IEEE Photinic Society's 23rd Annual Meeting, 2010
We present a detection module based on a linear array of Single-Photon Avalanche Diodes (SPAD) made in a standard CMOS technology. The monolithic chip is employed both to count photons at very high frame-rate (up to 4,000,000 frames/s, with 250 ns time tagging resolution) and to mark photon arrival time with 50 ps timing precision.

Planar technologies for SPAD arrays with improved performances

SPIE Proceedings, 2012
In the last years many progresses have been made in the field of Silicon Single Photon Avalanche Diodes (SPAD) thanks to the improvements both in device design and in fabrication technology. For example, the use of custom fabrication processes has allowed a steadily improvement of SPAD performance in terms of active area diameter, Dark Count Rate (DCR),

High performance compound semiconductor SPAD arrays

SPIE Proceedings, 2016
Aggregated compound semiconductor single photon avalanche diode (SPAD) arrays are emerging as a viable alternative to the silicon photomultiplier (SiPM). Compound semiconductors have the potential to surpass SiPM performance, potentially achieving orders of magnitude lower dark count rates and improved radiation hardness.

Characterization of SPAD Arrays: First Results

2006
SPAD detectors are very promising for astrophysical applications. Large arrays are crucial to cover as much of the focal plane as possible. STMicroelectronics has developed various monolithic arrays of SPAD. At present, the manufacturing of 5×5 arrays (each with an active area of 40 μm and pitch between adjacent pixels of 240 μm) is completed and ...
