The plate is moved in the orthogonal direction, the emitted light being collected by a suitable light guide and recorded by a photomultiplier. The emitted fluorescence light is directed to a photomultiplier. This gave us the relation between the energy of the third harmonic and the photomultiplier tube signal. The plastic scintillator was wrapped in aluminium foil except for the side facing the window of the photomultiplier. The light photons are detected by a sensitive photomultiplier, digitized and stored. Reynolds-averaged velocity measurements are obtained from the photomultiplier signal using the technique known as fast-sweep-rate sampling spectrum analysis. Each of the active species (electrons and ions) will emit a small amount of light which can be detected with a photomultiplier tube. The analyzed light was transformed to an electric signal by a photomultiplier tube. The optical section thickness was controlled by adjusting the confocal aperture of the photomultiplier tube and was held constant along with the gain setting. The goniometer hub could be rotated independently of the rotating arm which supported the photomultiplier tube. The separate colours were bandpass filtered and focused on two photomultiplier tubes. Next, the third to the 11th harmonics were calibrated based on the photomultiplier signal obtained using the vacuum monochromator. Angular variation of the scattered-light wave vector was provided by mounting the photomultiplier tube on a wide-range vertical goniometer which could be positioned to within 0.01". The emitted fluorescence was obtained through a dichroic beamsplitter (510 nm) and emission filter (530 nm) and collected by a photon-counting photomultiplier. A discrete sample of the angular intensity distribution is recorded during one revolution of the latter mirror, which is inclined a t 45" to transmit signals to a photomultiplier. The amount of light emitted can be measured by an avalanche photodiode, photomultiplier tube, or with a charged-coupled device camera (with or without a microchannel plate). However, due to the long duration of the experiment on each cell (up to 1 h), slow drift of the lamp output and photomultiplier high voltage was inevitable. Tree (1986) presented time-averaged spectra of the photomultiplier signal of a laser anemometer recorded in the vicinity of the mean junction vortex upstream of a circular-nosed wing. |
