Paper Abstract

We have considered the image formation due to a number of single and multiple apertures in their immediate vicinity. Under incoherent illumination the images are produced with an extremely high demagnification, typically of the order of 103. Analyses based on geometrical optics, Fresnel-Kirchhoff diffraction theory and the optical transfer function (OTF) have been used to characterize the images produced by pinholes, rectangular slits and rectangular transmission gratings. The high factor of demagnification has been advantageously utilized for numerous applications including image subtraction and phase object characterization. The reverse geometry producing highly magnified images has been discussed and applied to displacement metrology.
