| 摘 要： | 按照ISO/16063-11：1999《激光干涉绝对法振动校准》所述,激光干涉振动一次绝对校准方法主要有条纹计数法、最小点法与正弦逼近法三种,其复现频率范围为1Hz～10kHz.而德国联邦物理技术研究院（PTB）现已建立和保存的低频、中频、高频振动激光干涉一次绝对校准标准的复现频率范围则达0.1Hz～20kHz.此外,PTB还实现了旋转运动物理量值--角加速度的复现;其复现频率范围也达到0.3Hz～1kHz.作为曾在PTB1.22实验室进行过研究工作的访问学者,作者旨在通过对PTB所建激光干涉振动一次绝对校准标准的

| Abstract: | According to ISO/16063-11:1999 , It's been divided into three kinds of methods to reproduce absolutely the vibration value by laser inteferometry: the first is called fringe-counting method that it's applicable to frequency 1Hz-10kHz, the second called minimum-point method can be used for sensitivity magnitude calibration in the frequency range 800Hz-10kHz, the third of sine-approximation method is used for magnitude of sensitivity and phase calibration in the frequency range 1 Hz-10kHz. It's not only extended the frequency range to 0.1 Hz-20kHz for the vibration standards conserving in PTB to reproduce absolutely the linear vibration value, but also they can calibrate the angular acceleration for the frequency range 0.3 Hz-1kHz. |
