The recent developments in time-domain diffuse optics that rely on physical concepts (eg,
time-gating and null distance) and advanced photonic components (eg, vertical cavity …

Time-of-flight (ToF) sensors using light pulses or continuous waves allow accurate distance
measurements. Three-dimensional imagers can be based on an array of timing or time …

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 …

We present a CMOS imager consisting of 32× 32 smart pixels, each one able to detect
single photons in the 300-900 nm wavelength range and to perform both photon-counting …

Time-to-digital converters (TDCs) are vital components in time and distance measurement
and frequency-locking applications. There are many architectures for implementing TDCs …

Solid-state single photon detectors are playing a significant role in the development of high-
performance single-photon imaging systems for fluorescence lifetime imaging, time-of-flight …

This paper proposes a bin-width tuning method for a field-programmable gate array (FPGA)-
based delay line for a time-to-digital converter (TDC). Changing the hit transitions and …

Analog and digital SiPMs have revolutionized the field of radiation instrumentation by
replacing both avalanche photodiodes and photomultiplier tubes in many applications …

Time-to-digital converters (TDCs) are increasingly used as building blocks in biomedical
imaging, digital communication, and measurement instrumentation systems. When …

In this paper, a high resolution, high precision and ultra-low power consumption time-to-
digital converter (TDC) is presented. The proposed TDC is based on the gateable Vernier …
