Speech Title: Research on High-Speed Ultra-Precision Laser Interferometer and Its Calibration
Abstract: Laser interferometric displacement measurement (DMI) technology is a measurement technique that uses the wavelength of a laser as a scale and perceives displacement information through the frequency and phase changes of the interference spot. Due to its non-contact, high-precision, high-dynamic, and directly traceable measurement results, it is widely used in the characterization of material geometric properties, calibration of precision sensors, precision motion testing, and integration of high-end equipment.
In response to the urgent demand for high-end equipment research and development, Harbin Institute of Technology has successively explored traditional and new-generation high-speed ultra-precision laser interferometric measurement methods, instruments, and calibration technologies, providing key technical support and important common technical foundations for the research and development and production of high-end equipment.
演讲题目：高速超精密激光干涉仪及其校准技术研究
摘要：激光干涉位移测量（DMI）技术是一种以激光 波长为标尺，通过干涉光斑的频率、相位变化来感知位移信息的测量技术。因具有非接触、高精度、高动态、测量结果可直接溯源等特点，被广泛应用于材料几何特性表征、精密传感器标定、精密运动测试与高端装备集成等场合。
针对高端装备研发的迫切需求，哈尔滨工业大学先后探索了传统和新一代的高速超精密激光干涉测量方法、仪器及其校准技术，为高端装备研发生产提供了关键技术支撑和重要共性技术基础。仪器已用于
