摘要:
The invention relates to an interferometer (10) for real-time measurement of absolute distances and/or relative position movements between a first and a second machine part, comprising a measurement unit (20) and a reflector unit (40). The measurement unit (20) comprises a housing (21) having at least one wall that consists of a heat-conducting material, a plurality of measurement elements being arranged inside the housing (21). Said measurement elements comprise: a laser source (22), a Peltier element (24) and a digital control (23), and are thermally coupled to the wall of the housing (21) that consists of a heat-conducting material.
