Abstract: A three-dimensional shape measuring method by which measurement of a three-dimensional shape is realized with an improved precision. Grid patterns comprising a plurality of one-dimensional grids 1, 2 and 3, each having a period and direction different from those of the others, are simultaneously projected upon objects to be measured, using different colors for each of the one-dimensional grids 1, 2 and 3. Subsequently, a grid image deformed in accordance with the three-dimensional shapes of the objects to be measured is imaged, the grid image is separated by colors into one-dimensional grid components of each color, a phase for each of the one-dimensional grid components is detected, and then, measurement values of the three-dimensional shapes are obtained on the basis of the detected phases. At the same time, by imaging the objects to be measured by use of white light, color information on the objects to be measured are measured as well.

Abstract: Film of a known refractive index whose thickness is to be measured is illuminated by a white light beam. Two wave fronts from both sides of the film are directed to an interferometer. The wave fronts are out of phase in accordance with the thickness of the film. The two wave fronts are amplitude-split, respectively, by the beam splitter of the interferometer. Two of the split wave fronts are tilted by tilting means in the interferometer. The other two split wave fronts, as well as the two tilted wave fronts, are directed to an interference surface. Thus, there is formed a white interference pattern on the interference surface. The white interference pattern has a middle peak and two side peaks. The space interval between these peaks is measured by a scanner. By knowing the peak-to-peak interval, it is possible to discriminate the space interval between both sides of the film.
