title: Diffraction images of a general periodic rectangular wave object in a polarizing microscope with crossed polarizers.
abstract: Diffraction images of a general periodic rectangular wave object formed by a polarizing microscope with crossed polarizers have been investigated. Expressions for the intensity distribution in the images have been obtained. Results have been presented for the intensity distribution and contrast in the diffraction images of the system. A close similarity has been shown between the rectangular wave response corresponding to a particular bar width and the sine wave response.
