title: Shape measurement of curved objects using multiple slit-ray projections.
abstract: A method for the shape measurement of curved objects has been developed using multiple slit-ray projections and a turntable. The object is placed on a computer-controlled turntable and irradiated by two directed slit-ray projectors. An ITV camera takes a line image of the reflection from the object, and a computer calculates the space coordinates of the object surface. By using multiple projections, the total shape measurement of the object surface is attained accurately.
