This review is aimed at presenting the state-of-the-art of time domain (TD) functional near-
infrared spectroscopy (fNIRS). We first introduce the physical principles, the basics of …

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 …

This article reviews the past and current statuses of time-domain near-infrared spectroscopy
(TD-NIRS) and imaging. Although time-domain technology is not yet widely employed due to …

CMOS single-photon avalanche diodes (SPADs) have recently become an emerging
imaging technology for applications requiring high sensitivity and high frame-rate in the …

Single-photon avalanche diode (SPAD) based transient imaging suffers from an aberration
called pile-up. When multiple photons arrive within a single repetition period of the …

Diffuse optical spectroscopy (DOS) and diffuse optical imaging (DOI) are emerging non-
invasive imaging modalities that have wide spread potential applications in many fields …

We detail the design, construction and performance of the second generation UCL time-
resolved optical tomography system, known as MONSTIR II. Intended primarily for the study …

We present the first experimental results of reflectance Diffuse Optical Tomography (DOT)
performed with a fast-gated single-photon avalanche diode (SPAD) coupled to a time …

Fiber-optic probes are commonly used in biomedical optical spectroscopy platforms for light
delivery and collection. At the same time, it was reported that the inconsistent probe-sample …

This work reviews physical concepts, technologies and applications of time-domain diffuse
optics based on time-gated single-photon detection. This particular photon detection …
