Abstract
A measurement interferometer ( ) having a frame structure ( ), a laser source ( ), a detector ( ), a beam splitter ( ), a reference retroreflector ( ), a reference holder ( ) and a test retroreflector ( ). The reference rertoreflector ( ) and beam splitter ( ) are disposed in fixed relation to the reference holder ( ) to constitute a splitter-holder assembly ( ). The test retroreflector ( ) and the splitter-holder assembly ( ) are movable relative to each other and both are movably mounted on the fine structure ( ). Preferably, the test retroreflector ( ) is situated between the reference holder ( ) and the beam splitter ( ). In a particular embodiment the beam splitter ( ) is connected to the reference holder ( ) by a carbon composite rod ( ), and the test retroreflector ( ) is mounted on a probe ( ) made from a carbon composite. In one embodiment, the reference retroreflector ( ) is integral with the beam splitter ( ). There may be a vibration-dampening member such as a spring ( ) between the splitter-holder assembly ( ) and the frame structure ( ).
