Abstract:
The design and technical capabilities of the following systems are described 1 Copper Vapor Laser pulsed light source with spatial filter and collimator.2 Proximity focussed diode intensified linear CCD camera. 3 High speed multiplexed Analog to Digital Conversion system. 4 Monochromator system for point or line imaging of chemiluminescence. This instrumentation has been assembled to exploit several nonintrusive optical techniques to make measurements in a wide range of turbulent flows. The primary, but not exclusive, measurement technique to be implemented was Rayleigh scattering, imaged along a line as a function of time. A slightly modified version of the same apparatus was to be used in performing scattering measurements or liquid-phase laser- induced fluorescence measurements with the same temporal and spatial resolution capabilities. A second technique was to make use of a monochromator to analyze, and possibly image, chemiluminescence in a reacting flow in a wavelength- specific fashion, either at a point or along a line. The light source, the detection systems, and the data acquisition systems assembled under this funding will each be described.
