ABSTRACT:
An instrument for measuring a dimension of an object is disclosed including a rotatable disc defining at least one translucent involute slit proceeding from a base circle centered at the center of rotation of the disc and a diaphragm mounted adjacent the disc and defining a linear slit arranged on a line tangent to the base circle. The intersection of the involute slit and the diaphragm slit forms a translucent overlap zone, and an image of the object is projected onto the disc or the diaphragm in the region of the diaphragm slit oriented such that the dimension to be measured is parallel to the diaphragm slit.
