Paper Abstract

This paper reports the theoretical and experimental sensitivity of Fourier imaging (Fl) and the Fourier imaging system (FIS)'' respectively. The theory based on scalar diffraction which specifies these sensitivities is presented and discussed. Specifically the theoretical sensitivity of the Fl technique at a wavelength of 633 nm is determined to be 0. 003 nm while the experimental sensitivity of the FIS is approximately 15 nm. Both of these figures utilize a one-dimensional 1-pm rectangular diffraction structure for their calculation.
