    摘要: The present invention discloses microwave resonant absorption (MRA) of viruses through dipolar coupling to viral confined acoustic modes. The unique geometrical and mechanical properties of viruses can be reflected by the MRA frequencies, MRA linewidth, and the absorption selection rules of high-order acoustic modes. Combined these spectral characteristics with the mature microwave technology, this invention provides a novel physical mechanism to develop non-affinity-based rapid detection and identification of viruses. It can be applied in preliminary characterization on unknown or mutant viruses.

    摘要: A method for measuring an ultrashort optical pulse, in which third order autocorrelation of femtosecond (10−15 second) optical pulses was realized based on third-harmonic-generation (THG). A THG signal with three fundamental frequency photon contributed from three different split pulses of the ultrashort optical pulse is first generated. The three split pulses have time delays &tgr;1 and &tgr;2 in between. Then, the intensity of the THG signal is detected while varying the time delays &tgr;1 and &tgr;2 between the split pulses to obtain a triple correlation of the ultrashort optical pulse. The triple correlation and its Fourier transform are used to obtain the magnitude |Ĩ(&ngr;)| and the phase &agr;(&ngr;) of the ultrashort optical pulse intensity in the frequency domain, and the intensity of the ultrashort optical pulse in the time domain I(t) is determined using the magnitude |Ĩ(&ngr;)| and the phase &agr;(&ngr;) by inverse Fourier Transform.
