Abstract
There has been need for a simple device to measure with reasonable accuracy the degree of unsteadiness in 35-mm projector mechanisms, particularly where such mechanisms are overhauled and must be tested in a workshop. The following paper describes a simple technique which provides for an actual metering of the unsteadiness factor in terms of maximum displacement between any 2 frames during the running of a test film bearing on a suitable target.
