Context. A new extremely high speed photon-counting photometer, Iqueye, has been
installed and tested at the New Technology Telescope, in La Silla. Aims. This instrument is …

This paper describes the results obtained so far with AquEYE, a single photon counting,
fixed aperture photometer for the Asiago 182 cm telescope. AquEYE has been conceived as …

We present the preliminary results of the characterization of silicon detectors in terms of
Photon Detection Efficiency (PDE). The precision measurements are performed at controlled …

Aqueye+ is a new ultrafast optical single photon counter, based on single photon avalanche
photodiodes (SPAD) and a 4-fold split-pupil concept. It is a completely revisited version of its …

A comprehensive and in-depth characterization procedure for obtaining very accurate
measurements on silicon photomultiplier detectors (SiPMs) is here described. A large …

Previous and ongoing searches for extraterrestrial optical and infrared nanosecond laser
pulses and narrow line-width continuous emissions have so far returned null results. At the …

Since a number of years our group is engaged in the design, construction and operation of
instruments with very high time resolution in the optical band for applications to Quantum …

A comprehensive and in-depth characterization procedure for obtaining very accurate
measurements on silicon photomultiplier (SiPM) detectors is described here. A large amount …

In this contribution we present the results of the first morphological and electro-optical
characterization of Silicon Photomultipliers (SiPM) for nuclear medical imaging applications …

In the last years we have operated two very similar ultrafast photon counting photometers
(Iqueye and Aqueye+) on different telescopes. The absolute time accuracy in time tagging …
