This technique determines the droplet velocity by standard fringe mode LDA (see section 4.2.1), and establishes the droplet size by measuring the phase shift of light encoded in the spatial variation of the fringes reaching two detectors after traveling paths of different lengths through the droplets (Figure 4.7). The phase shift is measured by two detectors, each looking at a spatially distinct portion of the collection lens. This technique determines the

droplet velocity by standard fringe mode laser anemometry, and establishes the droplet size by measuring the phase shift of light encoded in the spatial variation of the fringes reaching two detectors after traveling paths of different lengths through the droplets (Fig. 1a). The phase shift is measured by two detectors, each looking at a spatially distinct portion of the collection lens.

4.2.3 Operating Conditions

A PDA system from Dantec Dynamics is used in the present study. The light source is a multi-line argon ion air-cooled laser (Spectra-Physics Model 177) operating at 488 nm and 514.5 nm with approximately output of 300 mW. In the transmitter unit, the laser light is color separated (514.5 nm for the axial component and 488 nm for the radial component) and the two beams are split into four and coupled into single mode glass fibers, which conducts them to the transmitting optics unit. One beam of each color is frequency shifted by 40 MHz through a Bragg cell for the purpose of direction recognition of the velocities. The polarization direction is adjusted perpendicular to the scattering plane. The scattering light is collected by a receiving lens where it is coupled into multimode fibers. After color separation by filters, the light reaches the photomultipliers and is transformed into electrical signals. The signals are processed by a covariance-processor (Dantec 58N80) of the PDA system. With this processor, the frequency and the phase shift of the filtered and amplified signals are determined. The signals are processed if the signal-to-noise of the burst of a droplet fulfills a minimum criterion.

The light source was a multi-line argon ion watercooled

laser (Coherent Innova 70) operating at 488 nm and 514.5 nm with approximately output power of 200 mW. In the fibre drive unit, the laser light was colour separated (514.5 nm for the axial component, 488 nm for the radial or tangential component) and the two beams split into four and coupled into monomode glass fibres, which conducted them to the transmitting optics unit. One beam of each colour was frequency shifted by 40MHz through a Bragg cell for the purpose of direction recognition of the velocities. The polarisation direction was adjusted perpendicular to the scattering plane. [...] The scattering light is collected by a receiving lens with a focal length of 400 mm, which is placed at a 30° off-axis forward scatter mode, where the scattering of light by refraction is in the dominant mode and yields a linear relation of particle size and phase between the photodetectors over the detectable size range of the instrument. After colour separation by filters, the light fell onto the detectors regions where it was coupled again into glass fibres to reach the photomultipliers and transformed into electrical signals. The signals were processed by a covariance-processor of the PDA system. With this processor, the frequency and the phase shift of the filtered and amplified signals are determined. The signals are processed if the signal to noise of the every burst of a droplet is -3 dB or better.

Anmerkungen

Nothing has been marked as a citation. Various modification have been made, most prominently the transference from BE to AE. Otherwise the original text has been left mostly intact. Seemingly unnecessary technical details have been cut out.
