Image differentiation with spatial incoherent light
In order to suppress the coherent artigact noise, a method of image differentiation by means of monochromatic incoherent line source is described. Differentiation filter is realized by making F. T. holographic filter from diffracting grating type differentiation mask. Experimental results show that noise reduction resulting from the line source is considerable.
