PCT No. PCT/AU82/00147 Sec. 371 Date May 2, 1983 Sec. 102(e) Date May 2, 1983 PCT Filed Sep. 1, 1982 PCT Pub. No. WO83/00921 PCT Pub. Date Mar. 17, 1983.A method of forming a color image using image signals generated by a scanning electron microscope. Three different image signals are generated, a first representing a monochromatic image derived from secondary electrons of energies over a broad range of energies, a second representing a monochromatic image derived from secondary electrons having high energies only and a third representing a monochromatic image derived from backscattered electrons. The three so generated image signals are used to construct the color image by assigning respective colors of an additive primary set to the monochromatic images represented by the three signals. The image signals are combined to form the color image by a process which results in additive mixing, in the color image, of the three monochromatic images.
