Interpretation of spray behavior in complex aerodynamic flows using phase Doppler interferometry and planar-liquid-laser-induced fluorescence. Holographic interferometry with an injection seeded Nd:YAG laser and two reference beams. Decker AJ. The performance of twin injection seeded Nd:YAG lasers is compared with the performance of an argon-ion laser for recording dual-reference-beam holograms in Agfa 8E56 emulsion. Holographic interferometry has been used to study the flow on the inlet of a supersonic combustion ramjet. A Q-switched Nd:YAG laser with a pulse duration of about 10 ns was used to generate a beam of light at tunnel and constituted the “no-flow” or reference beam of the interferogram. A second hologram was recorded during the Compact and portable holographic camera using photorefractive the hologram is illuminated the same reference beam that has served for the recording. One generally distinguishes sev-eral procedures. Used for illumination. Presently, continuous Nd:YAG lasers emitting up to … for high speed flows. DSPI also imposes requirements on some laser properties such as coherence length and beam divergence, which are not essential for PIV.The works mentioned above report the set up of DSPI in a slow convective flow with a He-Ne laser and in a wind tunnel flow with a pulsed Nd-YAG laser and fiber optics.

National Aeronautics and Space Administration.] The laser and optics were mounted on stable optical tables placed either side of t he test section of the facility. Dust is a signicant problem in this environment and the equipment was protected large covers placed on top of the tables. To record an image, the 532 nm output from an injection-seeded pulsed Nd:YAG laser was use d A.J.

Interferometric techniques have long been used in studying flow fields. A beam of light is divided into two, with one part, the object beam, passed through the flow and the other, the reference beam, passed around. A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission. The term "laser" is an acronym for Light Amplification Stimulated Emission of Radiation. Laser light is usually spatially coherent, which means that the light either is emitted in a narrow, low-divergence beam, or can be converted into one with the help of optical components such Though most of previous PLD studies of TiN film used a titanium target with reactive gases, the study presented in this chapter has significant features of (1) a hot pressed target of crystalline TiN powder and (2) third harmonic of injection-seeded Nd:YAG laser which have temporally smoothed Gaussian with a constant pulse energy. Appl. Phys. B manuscript No. (will be inserted the editor) Nd-YAG laser followed later work [70,71] including the application to the monitoring of bridge movements with reference mirror, object, beam splitter (BS), photodetector, RF-filter and evaluation electronics. The Improving the quality of phase maps in phase object digital holographic interferometry finding the right reconstruction distance Eva-Lena Johansson,* Lars Benckert, and Mikael Sjödahl For frequency-doubled Nd:YAG and Nd A transmission hologram is a record of the interference between the light scattered from an object and a reference beam. In this setup, the two beams are produced splitting the input-beam single-frequency laser into two components. When the developed hologram is illuminated with a laser beam Figure 1: Schematic of off-axis HPIV recording of the particle field. The two laser beams from the injection-seeded dual YAG laser, separated a short time interval, are splitted the beam handling unit into 3 beams: The illuminating beam, reference 1 and reference 2.

It had a diameter of ˚ ˇ 1 mm and reduced radiation from the arc additionally. An injection-locked laser is disclosed. The injection-locked laser comprises a seed laser (1), an oscillator (O) into which a certain component of light output from the seed laser is injected as seed laser light, a frequency converter (6) which shifts a frequency of the remaining component of the light output from the seed laser, a photodetector (9) which detects light obtained synthesizing Seeded solid-state laser bolsters.particle image velocimetry. From two-dimensional flow dynamics to real-time velocity profiles, particle image velocimetry (PIV) helps discern complex fluid flows in applications ranging from aerospace engineering to automotive-engine and body design. High-performance holographic technologies for fluid-dynamics experiments. D’Auria et al. 1973), in which the reference beams differ the angle of their incidence, were recorded using two consecutive pulses of a Nd:YAG laser and reconstructed using the phase-conjugate approach. two laser beams were each divided, routed into two separate reference-beam channels, and combined carefiflly in a single object-beam channel. The argon-ion inspections were performed accurately displacing the blade tip between exposures of the double-exposure hologram.
