Abstract:
A device for establishing an aberration-free delivery system for use in evaluating an optical specimen, wherein the system directs light along a beam path toward the specimen, said device comprising:a detector; an active mirror positioned on said beam path between said system and said specimen; a first beam splitter positioned on said beam path between said active mirror and said specimen for directing a portion of the light radiated from said system toward said detector for creation of a first wavefront, said first wavefront having characteristics of optical aberrations in said system; a means for generating a signal indicative of said first wavefront, said signal generating means being connected to said active mirror for selectively programming said active mirror with said signal to establish an aberration-free wavefront for light from said system incident on the optical specimen; a second beam splitter positioned on said beam path between said first beam splitter and said specimen for directing a portion of the light reflected from said specimen toward said detector for creation of a second wavefront, said second wavefront having characteristics of optical aberrations in said specimen; and a means for analyzing said second wavefront to evaluate the optical specimen.
