Apparatus for Measuring Holographic Lens Aberration Parameters.
Abstract
The patent application concerns an instrument for measuring various parameters that are analogous to the aberrations that may exist in holographic lenses and other energy diffraction apparatus. This contains a laser energy source; a pair of masks for controlling precisely the path of the light from said laser energy source, so that it may be used as a reference parameter; a rotatable mounting table for holding the holographic lens being tested in an appropriate position in the path of said reference laser light path; a microscope positioned to receive predetermined laser light rays that have been diffracted by the holographic lens being tested; and a support bench upon which all of the aforesaid elements may be mounted, so that their respective relative positions may be controlled in such manner that they form a unique geometrical configuration and combination.
