Abstract:We present a proof of concept prototype of a time-domain diffuse optics probe exploiting a fast Silicon PhotoMultiplier (SiPM), featuring a timing resolution better than 80 ps, a fast tail with just 90 ps decay time-constant and a wide active area of 1 mm 2 . The detector is hosted into the probe and used in direct contact with the sample under investigation, thus providing high harvesting efficiency by exploiting the whole SiPM numerical aperture and also reducing complexity by avoiding the use of cumbersome fiber bundles. Our tests also demonstrate high accuracy and linearity in retrieving the optical properties and suitable contrast and depth sensitivity for detecting localized inhomogeneities. In addition to a strong improvement in both instrumentation cost and size with respect to legacy solutions, the setup performances are comparable to those of state-of-the-art time-domain instrumentation, thus opening a new way to compact, low-cost and high-performance time-resolved devices for diffuse optical imaging and spectroscopy.

“…Assuming that all these sources of noise are wide-sense stationary, statistically independent random processes with gaussian distribution, the total standard deviation of the resulting process is computed as, σ Fig. 6 (b) shows simulation results of the noise by routing, σ route , and the total temporal noise, σ spad+route , assuming that the SPAD jitter is 42.6 ps sigma [3]. It is observed that the SPAD jitter is dominant for the temporal jitter.…”

“…In digital SiPMs (D-SiPMs) on the contrary, all of the SPAD outputs are combined together by means of a digital OR, and the output is directly routed to an on-chip time-to-digital converter (TDC) to reduce external components and temporal noise as shown in Fig. 1 (b) [2], [3]. Timing resolution for single-photon detection is limited by SPAD jitter and circuit noise, as well as systematic skew due to imperfectly balanced routing.…”

This paper presents the analysis of timing resolution for a digital silicon photomultiplier (D-SiPM) using a SPICE simulator. A D-SiPM has more than a hundred of pico seconds timing resolution for single-photon detection due to detector jitter, circuit noise and routing skew. Especially, circuit noise and skew depend on the SiPM design strongly. To investigate how single-photon timing resolution is related to architectural choices and design parameters, we have simulated the timing resolution by sweeping the design parameters: the transistor size and the transistor channel length, wire resistance and capacitance. We considered D-SiPMs of different sizes and with a variety of signal distribution architectures.

“…28,29 Still, the state-of-the-art for SiPM technology is not yet fully miniaturized, but due to the possibility to integrate into a single silicon chip in both detectors and ancillary electronic circuits, 30,31 SiPMs represent the most attractive technology for the next-generation of DOT systems. Therefore, the demonstration of SiPM suitability also for TD-DOT could open the way to novel immediate perspectives due to the possibility to conceive low-cost and reliable multichannel systems.…”

Abstract. Silicon photomultipliers (SiPMs) have been very recently introduced as the most promising detectors in the field of diffuse optics, in particular due to the inherent low cost and large active area. We also demonstrate the suitability of SiPMs for time-domain diffuse optical tomography (DOT). The study is based on both simulations and experimental measurements. Results clearly show excellent performances in terms of spatial localization of an absorbing perturbation, thus opening the way to the use of SiPMs for DOT, with the possibility to conceive a new generation of low-cost and reliable multichannel tomographic systems. © The Authors.
