Abstract: An optical analog pseudocolor technique in the object space is described to encode the spatial frequency content of an object transparency. The effect is obtained by means of a suitable matching of the source power spectrum with the transmittance characteristics of a non-blocked interference filter as a function both of the wavelength and the angle of incidence. Experimental demonstrations on object gratings is presented.
