  • Abstract
    In this paper, we have developed an interferometeric system for measuring three-dimensional position, which measure x, y and z directions separately. This system produces a single data set from which all three positions can be derived analytically. The zero position of the system does not need to be reset before a measurement can be made, and the position does not require tracking between measurements.
