Paper Abstract

In microgravitation experiments the shadow profile of molten and undercooled metallic alloy spheres of 7 - 8 mm diam. are imaged by means of LED illumination and backlight reflectors made from thin tantalum foil, with rolled grooves in oblique orientation. In spite of their macroscopic structure the reflectors permit measuring the contours of the oscillating spheres for viscosity and surface tension calculations.
