Interactive Use of a Time-shared Process Control Computer in Electrophotographic Sensitometry

The usefulness of electrophotographic exposure sensitometry as a means of characterizing and evaluating new photoconductor materials has been extended by coupling the experiment to an on-line computer. This automated system provides several new functional capabilities not realistically attainable in manual operation and drastically reduces the time lag in the exchange of information between research workers who prepare materials and those who evaluate the materials. These various improvements have been achieved by extensive use of interactive graphic techniques and a user-oriented data-base organization.
