This detector combines the most desirable features of two fundamentally different types of traditional optical detectors into one system. The Mepsicron-II offers the exceptional ultralow-light sensitivity, low-noise, high signal-to-noise ratio and time-resolved capabilities of a digital, single-photon-counting photomultiplier (PMT) combined with the full X-Y positionsensitivity of a 1-D or 2-D ...

The properties of a 50 mm × 50 mm × 30 mm monolithic LaBr3:Ce scintillator crystal coupled to a position-sensitive multi-anode photomultiplier (PMT, Hamamatsu H9500), representing the absorbing detector of a Compton camera under study for online ion (proton) beam range verification in hadron therapy, was evaluated in combination with either absorptive or reflective crystal surface coating. This...

In this paper, we show a renewed approach to the generalized methodology for atmospheric lidar assessment, which uses the dimensionless parameterization as a core component. It is based on a series of our previous works where the problem of universal parameterization over many lidar technologies were described and analyzed from different points of view. The modernized dimensionless parameteriza...

A novel ultraviolet pulsed-light source with a digitally controlled amplitude has been developed and used to determine the response of the BURLE 8850 photomultiplier tube for light intensities close to that corresponding to single photoelectrons to those well beyond the linear response region. r 2003 Elsevier Science B.V.

Diffuse optical tomography (DOT) is a rapidly growing discipline in recent years. It plays an important role in many fields, such as detecting breast cancer and monitoring the cerebra oxygenation. In this paper, a relatively simple, inexpensive, and conveniently used DOT system is presented in detail, in which only one photomultiplier tube is employed as the detector and an optical multiplexer ...

We demonstrate experimentally ultrafast three-photon counting by three-photon absorption in a GaAsP photomultiplier tube at the wavelength range of 1800-1900 nm, and analyze its sensitivity and time response. Pulse energy of ∼500 fJ is shown to be detectable for ultrafast 170 fs pulses. The presented three-photon counter may serve as a unique tool for ultrafast quantum state characterization as...
