Abstract

A model of an infrared scanning densitometer was constructed using the basic designs developed by Hisler and Casinelli in their 1970 research work, and by Beaupre and Jasper in their 1971 research work, plus several new ideas which greatly improved the reliability and usefulness of the machine. Among the changes were: use of an infrared sensitive photomultiplier tube on recommendation of Hisler and Caslnelli; Z axis modulation for oscilloscope display, a new idea; and addition of a diffuser to illuminate the sample to provide better correlation between wet and dry densities, on recommendation of Dr. Schumann.
