    • A method and apparatus are provided for detecting tremors induced in a subject that are indicative of stress, emotion, fatigue, deception or other similar psychological states. The apparatus includes a signal source for directly applying an excitation signal having a predefined amplitude and frequency to the subject so as to induce the tremor. The apparatus also includes a Doppler system for irradiating the subject with electromagnetic radiation and for detecting the electromagnetic radiation returning from the subject following modulation by the induced tremor. The Doppler system also analyzes the returning electromagnetic radiation to determine at least one of an amplitude of the induced tremor and a phase shift of the induced tremor relative to the excitation signal provided by the signal source. The amplitude and/or phase shift of the modulated electromagnetic radiation provide information regarding the stress, emotion, fatigue, deception or other similar psychological states of the subject.
    • 提供了一种用于检测在受试者中诱发的指示压力,情绪,疲劳,欺骗或其他类似心理状态的震颤的方法和装置。 该装置包括用于将具有预定义的振幅和频率的激励信号直接施加到受试者以引起震颤的信号源。 该装置还包括用于用电磁辐射照射受试者的多普勒系统,并且用于检测由被诱导的震颤调节后从受检者返回的电磁辐射。 多普勒系统还分析返回的电磁辐射以确定诱发震颤的幅度和诱发震颤相对于由信号源提供的激励信号的相移中的至少一个。 调制的电磁辐射的振幅和/或相移提供关于受试者的压力,情绪,疲劳,欺骗或其他类似心理状态的信息。
