Abstract

A description of the apparatus and the method of measurement are given. The time necessary for taking the photographs is very short and the parts to be measured not touched. Roughnesses of 0.5 to 10 mil. deep and o.1 to 1 inch wide are measured with a reasonable accuracy with the apparatus in the existing version.
