into customer-supplied hardware, readily adaptable to
suit customers' special needs, easy to align
High retroreflector translation rates
Tolerate large retroreflector angular misalignments
Fiberoptic-coupled sensor heads
Cause no thermal interference
Employ signal-acquisition and signal-transmission
hardware immune to electromagnetic interference
Employ He-Ne lasers with high frequency
stabilities as length standards
Correct for effects of environmental
influences on laser wavelength
