Image Synthesis

Not Accessible

Abstract

Optical-system point spread functions in the form of spot diagrams, taking due account of aberrations in the presence of diffraction, are used to synthesize pictorial images. Experimental work in which a versatile image synthesizer is used to synthesize images of random geometrical patterns and pictorial test objects in the presence of spherical aberration, coma, astigmatism, and coma plus astigmatism, with and without diffraction, is discussed. It is shown that considerable discrepancy arises on ignoring the diffraction effects when aberrations are small. Further applications of the image synthesis technique in electro-optical systems are suggested.
