28. The supporting sleeve is connected by a series of gears to a motor, allowing rotation in either direction. The impeller is constructed of a 10.16-cm-diameter 0.46-cm-thick acrylic disk mounted on a 1/2-inch (1.27-cm) aluminum shaft that is mounted with a 2.5-cm-tall needle bearing to prevent radial movement. Both motors are controlled manually with Bodine speed controls. An outer rectangular containment vessel is used to minimize optical effects due to curvature.
29. A Liconix 4240NB helium-cadmium constant-wave laser is used with 442-nm blue optics installed. The power rating at this wavelength is a nominal 40 mW and is verified at 36 mW with an Ophir Optronics laser power meter. The sheet is created by using a cylindrical lens mounted on the laser head and aligned such that the sheet falls on the center line of the impeller shaft.

32. Each needle has a small radius bend ∼3 cm from the end to allow it to project horizontally into the flow. Pressurizing the supply chambers feeding the needles controls the injection rate. To prevent dye "tails" upon repositioning or removal of the needles, the supply pressure is removed and a slight vacuum is applied.
