Abstract

Interferometric setups can be used as spatial frequency filters. The use of a polychromatic point source allows spatial filtering to be converted to color coding of spatial frequency. The effect of interferometers on various kinds of object including textured objects in polychromatic illumination is investigated, using a classification of interferometers according to whether the image to be processed is split axially or transversally when seen through the arms of the interferometer. Experimental examples are shown.
