Abstract

See full text

The present invention provides apparatus and methods for measuring the optical density of a fluid by measuring the light transmission through a reconfigurable optical path. The optical path is reconfigured by the deflection of an elastic membrane wherein the optical path length through the fluid is determined by the position of the membrane relative to a fixed surface. The optical density can be determined from two measurements with different optical path lengths through the fluid.
