The theoretical basis and structure of a new moire apparatus by projecting parallel light are described. With the aid of this device, the same intervals of contour lines are obtainable, irrespective of the moire fringe order, which represents the ordinal number of each fringe counted from a grating. This constancy of contour intervals could not be accomplished by our previous apparatus with radiating light (Terada 1973). The value of contour intervals is selected optionally by changing a grating pitch or a projecting angle of a beam of light on to the grating. This apparatus, in comparison with our previovs one, is smaller in size, lighter in weight and more portable. The apparatus introduced in the present paper is more applicable than our previous device for the contourography of a small area or parts of the human body such as the face, breast and so on. Being restricted by the diameter of the field lens, the present devise is not suitable for the whole human body. This technique with parallel light is to be applied along with the previous system with radiating light according to the purpose of our study.
