Optical and computational components are combined to form high precision, six degree-of-freedom, single-sided, noncontact position measurement systems. Reflective optical targets are provided on a target object whose position is to be sensed. Light beams are directed toward the optical targets, producing reflected beams. Electrical signals are produced by movements of reflected beams across position-sensitive detectors, such as lateral-effect photodiodes. The signals are transformed to provide measurements of translation along and rotation around three nonparallel axes which define the space in which the target object moves.
