摘要 | We propose a high-precision 2D grating displacement measurement system based on double-spatial heterodyne optical path interleaving. The system is based on Doppler-steering interferometry of 2D gratings, heterodyne interferometry, and double-spatial element-staggered configuration. We obtain long-stroke and high-precision real-time 2D displacement information using the optical phase change and interference signal decoupling caused by the 2D grating. The system is tested experimentally and compared with a laser interferometer, and found to have a measurement resolution within 3 nm. The error within a measurement of 40 mm is better than +/- 175 nm and +/- 150 nm in the 2D grating directions. The design is then optimized and tested, and the resulting error within the 40-mm range is better than + 50 nm and -40 nm in the X-direction and + 100 nm and -80 nm in the Y -direction. The results show that the proposed configuration improves the accuracy of the measurement system, is suitable for engineering testing, and has the potential for further improvement. |
