Sources of Error in Absolute Distance Interferometry



Jack A. Stone Jr., Alois Stejskal, Lowell P. Howard


In this paper we describe the status of our research on the use of diode lasers for absolute distance interferometry, and we discuss the major sources of uncertainty that limit the accuracy of this technique for distance measurement. We have primarily employed a 670 nm external cavity diode laser as the tunable source for our interferometer, but currently we are developing a system based on an 852 nm distributed Bragg reflector laser. These two lasers have very different strengths and weaknesses; the primary sources of uncertainty in length measurement depend on which laser is employed.
