This paper describes the setting up of a moire topographic system used to measure three-dimensional convex and concave surfaces of moulded brassiere cups. The essential features of the system consisted of a photographic instrument which precisely controlled the position of the light source, the camera, the grid and the cup sample. As the uniformity of the grid was most crucial to produce a high contrast moire picture, a photochemical machined grid plate was developed, and a pneumatic grid translation device was incorporated into the system to produce a clear image. The tolerance of the instrumental error was derived by the law of error propagation and the confidence with the moire set-up was assured.
