An iris diaphragm-based interface for use in eriometry / B. Kirk.: M38-13/80-20E-PDF
"Eriometry, the estimation of the size distribution of a set of fineparticles from their group diffraction pattern, has shown considerable potential for industrial application. This report describes a new and inexpensive method for interfacing the eriometer to a mini-processor. The interface consists of an iris diaphragm placed in the diffraction plane with subsequent focusing onto a single photodetector. The system has the advantage of integrating over any angular variations in the diffraction pattern without requiring a complex photodetector. The interface is applicable to the sizing of monodisperse powders as well as to the determination of size distribution of polydisperse samples. Some potential problems which may arise in the application of this technique are also investigated"--Abstract, page i.
