本文介绍了一种利用多普勒效应测量眨眼的实验方法。在认知科学文献中，眨眼被认为是一种复杂的现象，是高级神经过程的代表。我们开发了一种实验装置，其中使用多普勒传感器伴随着加速度计和EOG（眼电图）记录进行眨眼测量。从实验结果中，我们发现与眨眼相关的多普勒频率包含一个2hz的主导频率。最后，我们发现当眨眼同时伴有头部和身体运动时，利用主成分分析（PCA）可以分离眨眼信号。
In this report, we introduce an experimental method for eyeblink measurement by utilizing Doppler effect phenomena. In the cognitive science literature, eyeblink has been proposed as a complex phenomenon and acts as a representative of higher nervous processes. We developed an experimental setup in which the measurement of the eyeblink was conducted using a Doppler sensor accompanied by an accelerometer and an EOG (electrooculography) recording. From our experimental results, we found that the Doppler frequency related to blinking contains a dominant frequency at 2 Hz. Finally, we showed that when blinking is accompanied with head and body movements, eyeblink signal is separable by deploying the principal component analysis (PCA).
