Claim 13:
14. A method of inspecting an object, the method comprising:
positioning the object in a detection zone;
capturing, by an image sensor, a background image of the detection zone in the absence of a flowable scattering medium;
obtaining, by a processor, a background signal from the background image;
introducing the flowable scattering medium into the detection zone;
emitting, from a light source, a light beam in a direction that passes through the detection zone;
capturing, by the image sensor, a measurement image of the detection zone;
removing, by the processor, the background signal from the measurement image;
determining, by the processor, a boundary of a scattered signal region in the received measurement image; and
calculating a geometrical property of the object from the boundary of the scattered signal region.
