ABSTRACT
A Fourier analysis of the optoelectronic signal obtained from internal reflections of light inside a drop, which has been mechanically excited has been undertaken. A study using a range of liquids has revealed the existence of the drop vibration modes on pendant drops. The relationships of the various frequency components to the properties of the test liquids have been investigated. Studies have been undertaken into the consistency of these effects to determine whether there exists a quantitative instrumental basis for exploiting this knowledge to yield physical properties of small volumes of liquids.
