| 英文摘要: |
| In order to solve the problem of inaccurate measurement of vibration response of specimens with very low laser reflective intensity under continuous high temperature environment, a high temperature vibration measurement technique based on laser Doppler principle is proposed. This paper studies the enhancement of laser reflection signal, the post-processing of time-domain response data, and the thermal protection of laser vibrometer, and verifies the scientificity and reliability of this method through experiments. |
