Abstract

For the purposes of this paper, the measurement of shapes by optical noncontact methods is divided into two categories: 'simple' shapes, and 'complex' ones. Simple shapes are considered to be those that are near flat or spherical, and can be tested using conventional optical methods. Complex shapes are those that depart from flatness or sphericity by an appreciable amount, and currently need alternative test methods. A number of ways of testing complex shapes are described, and their relative merits are discussed.
