ABSTRACT:
A transparent plate and a process for the preparation thereof whose transparence at every point is a function of the coordinates of this point. A three-dimensional form representative of said function is made which has a base of a contour homothetic to that of the transparent surface to be made, and the thickness measured from the base is proportional to the values of the function, the form being made from a material which absorbs X-rays. A radiograph of this three-dimensional form is then made on the desired scale, and the transparent plate is the support of the radiograph thus obtained.
