This study summarizes several different methods that may be used to obtain the high frequency difference that is required in high-speed laser interferometers to support the advances made in mechanical manufacture and measurement techniques. A design for a dual-frequency interferometer with a frequency difference of 5 MHz and a bi-reflecting film cavity mirror is proposed, which satisfies application requirements and the need for reducing cost solutions. The characters of its frequency stabilization and polarization properties are tested. The theoretical performance is confirmed through experimentation. Finally, a laser interferometer is successfully constructed using this type of laser tube and is tested at a movement speed of 1 m sec-1. |
