ABSTRACT:
A laser linear measurement system wherein a laser beam is generated and directed to an interferometer and reflected by a retroreflector movably mounted on a carriage or other component and adapted to travel forward to a set point, the said retroreflector having means adapted to be fulcrumed to move forwardly or rearwardly on an arc to reflect a parallel beam to the linear measuring interferometer and secure a true linear measurement of an object to be measured.
