The development of steady State and lifetime fluorescence instruments for real time in situ aquatic chemistry measurements
… is used along with a 266 nm Q-switch laser, fast photomultiplier tube (PMT), and computer controlled monochromator to build a small fluorescence lifetime instrument. The instrument is tested with solutions of low concentration pyrene to demonstrate its ability to identify small, long-lived …

Light in Living Systems: Ultra-Weak Photon Emission and Fluorescence Lifetime Imaging of Cellular Dynamics
… Part II provides comparative analysis of photomultiplier tube (PMT), electron-multiplying charge-coupled device (EMCCD), and Single-photon avalanche diode (SPAD), highlights the challenges of resolving signals at the edge of noise, while modelling of mitochondrial electron transport chain …

Design of a 3-D rapidly scanning laser Doppler velocimeter with low SNR signal processing
… position of the receiving optics, and only one photomultiplier tube (PMT) is needed to receive the signals for all three velocity components. A data acquisition, control and processing system has also been designed for use with the RSLDV. The PMT signal and location of the measurement volume are …

Detection of vapor phase mercury species by laser fluorescence methods
… detection schemes, Charge Coupled Device (CCD) photomultiplier tube (PMT), are applied for the measurement of photofragment fluorescence. The performances of these two systems are compared in the dissertation. A supersonic jet is combined with resonance fluorescence for detection of elemental …

Advances in Raman hyperspectral compressive detection instrumentation for fast label free classification, quantitation and imaging
… in the +12° and -12° by two photon counting photomultiplier tube(PMT) detector modules. The new spectrometer avoids a double pass through the optics and hence has fewer losses associated due to reflection transmission of the optics. Full spectral measurements are made by consecutively …

Gravity Wave and Turbulence Transport in the Mesopause Region
… photon noise error but leads to challenges with photomultiplier tube (PMT) saturation at the same time. Corrections to this effect can be measured in a laboratory setting but may have large uncertainties at high photon count rates. Results show that this laboratory-correction can induce large …
