Diffraction theory of the method of the caustic for measurement of optical surfaces
An examination was made of diffraction effects that become apparent when measuring optical surfaces by the method of the caustic and direct observation of the zone. The sensitivity was calculated for several wire diameters or focal positions. The optimum wire diameter is 0·6 of the diameter of the d...

An examination was made of diffraction effects that become apparent when measuring optical surfaces by the method of the caustic and direct observation of the zone.
