    Notes: Abstract A portable laser sheet illumination source for flow visualization experiments has been developed utilizing fiber optic cable and standard optical bench components. This technique improves the convenience and safety aspects of using laser light by containing the concentrated laser energy inside a flexible and shielded fiber cable. Transmission efficiencies up to seventy-five percent have been obtained with a twenty meter long fiber cable and careful alignment of optical components. The current optical configuration can transmit a two-watt Argon-ion laser beam and produce a sheet one-half by one meter in size and approximately two to three millimeters in thickness.

    Near-wall, three-dimensional turbulence measurements: A challenge for laser velocimetry (1989)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: A new laser velocimeter approach is presented, which has distinct advantages in near-wall, two- and three-dimensional turbulence measurement applications. The approach does require placing a probe into the flow; but in return, there are some important benefits, such as, the direct measurement of the crossflow velocity, w, at a grazing incidence, and the ability to size optical components for the scale of the flow rather than the size of the facility. Promising resuls were obtained with this approach for a two-dimensional turbulent boundary layer.
