Title: Apparatus for determining the filling pressure of a plurality of microballoons

Abstract

An apparatus is described for determining the filling pressure of a plurality of microballoons, which comprises in combination: a. an optically transparent plate having a substantially flat surface; b. a rod affixed to the substantially flat surface of the optically transparent plate for removably attaching the microballoons, the rod being located substantially parallel to the transparent plate, and having a sticky substance thereon; and c. means for interferometrically scanning each of the microballoons both before and after the filling thereof in order to determine the gas fill pressure. The individual microballoons are attached sufficiently rigidly to the rod to permit the means for interferometrically scanning each of the microballoons to measure substantially the same microballoon orientation before and after the filling thereof.
