Abstract
A pulsed laser densitometer system measures highly optically dense samples. A pulsed laser beam pulse is split so that part of the beam pulse is directed through an optical delay path. The delayed beam pulse is then brought into the same path as the beam pulse transmitted through the sample and both beam pulses are fed through a detector. The output of the detector contains the optical density information in the ratio of the pulse amplitude of the transmitted pulse to the delayed pulse.
