Over the last decade, the recognition of the potential value of augmented reality (AR) and other human-machine interfaces has been growing. These applications are all based on depth sensing technologies. Among various depth sensing technologies, the Time-of-Flight (ToF) approach is emerging as a widely applicable method because it has the...

The imaging performance of clinical positron emission tomography (PET) systems has evolved impressively during the last ∼15 years. A main driver of these improvements has been the introduction of time-of-flight (TOF) detectors with high spatial resolution and detection efficiency, initially based on photomultiplier tubes, later silicon...

Employee behavior plays an important role in the occurrence and prevention of incidents, affecting safety margins. In this study, we examine the potential impact of incidental learning on human behavior in the presence of variation in task design. Incidental learning is the day-to-day on-the-job learning that occurs unintentionally. This...

Carimatto, A.J. (author)
Multi Digital Silicon Photon Multipliers (MDSiPM), as image sensors, are utilized to calculate and estimate the properties of the incident light. These properties include spatial location of hits, intensity or number of photons and time of arrival. Some characteristics can be more important than others depending upon the problem at hand. Among...

Most current proximity sensing methods fail the stringent requirements of modern smartphones. A position-sensing device (PSD) requires a laser placed some distance away from the sensor, intensity-based solutions are sensitive to changes in reflectivity, and ultrasound-based sensors cannot measure small distances because of resonance. With modern...

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 architecture usually features high fill factor at small pixel pitch and energy efficient...

The aim of this research is to explore the potential advantages of SPAD imagers used in microscopy. An ideal microscopy detector requires high sensitivity (high quantum efficiency QE or photon detection probability PDP), photon counting operation, low noise (dark current or dark count rate), timing resolution in the order of 100 ps, frame rate...

We present a high-performance back-illuminated three-dimensional stacked single-photon avalanche diode (SPAD), which is implemented in 45-nm CMOS technology for the first time. The SPAD is based on a P<sup>+</sup>/Deep N-well junction with a circular shape, for which N-well is intentionally excluded to achieve a wide depletion region, thus...

A fault-tolerant quantum computer with millions of quantum bits (qubits) requires massive yet very precise control electronics for the manipulation and readout of individual qubits. CMOS operating at cryogenic temperatures down to 4 K (cryo-CMOS) allows for closer system integration, thus promising a scalable solution to enable future quantum...

In today's digital life, security and encryption are becoming more and more important. As random number generators are a fundamental block of security and encryption, it is crucial to guarantee that these devices operate securely. Random numbers are usually generated in two ways; pseudo random number generators (PRNGs) and true random random...

The paper presents a camera comprising 512 × 128 pixels capable of single-photon detection and gating with a maximum frame rate of 156 kfps. The photon capture is performed through a gated single-photon avalanche diode that generates a digital pulse upon photon detection and through a digital one-bit counter. Gray levels are obtained through...

In this thesis, the research on silicon-based CMOS-compatible PureB technology was continued with the goal of enabling a PureB process module that could be added as a back-end module to wafers from a CMOS foundry. The properties of PureB layers deposited at low-temperature, particularly those deposited at 400°C were studied in more detail, among...

We report on the characterization of single-photon avalanche diodes (SPADs) fabricated in standard 140-nm silicon on insulator (SOI) complementary metal-oxide-semiconductor (CMOS) technology. As a methodology for SPAD optimization, a test structure array, called SPAD farm, was realized with several junctions, guard-ring structures, dimensions,...

An imager for optical tomography was designed based on a detector with 128x128 single-photon pixels that included a bank of 32 time-to-digital converters. Due to the high spatial resolution and the possibility of performing time resolved measurements, a new contact-less setup has been conceived in which scanning of the object is not necessary....

Imaging techniques based on time-correlated single photon counting (TCSPC), such as fluorescence lifetime imaging microscopy (FLIM), rely on fast single-photon detectors as well as timing electronics in the form of time-to-digital or time-to-analog converters. Conventional systems rely on stand-alone or small arrays (up to 32) of detectors and...
