    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.

    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： This invention relates to a vacuum-pump sucker for high-resolution microscopy comprising a sucker body and a transparent plate. The vacuum-pump sucker is designed as a stabilizer for sample stabilization in a clinical optical virtual biopsy system with sub-micron resolution. The sucker is connected with a vacuum pump. As the vacuum pump pumps out air or gas, tissues around the imaged area will be sucked by the sucker and the distance between objective lens and the imaged tissue can be stabilized. In this way, the stability and resolution of the clinical biopsy system can be greatly improved.

    摘要： A waveguide for guiding terahertz waves with wavelength ranging 0.1 mm-3 mm, includes a cladding tube made of a metal-free dielectric material, and a core filling a transmission space defined by the cladding tube. The core has a minimum width or diameter larger than the wavelength of the terahertz wave guided by the waveguide. The thickness of the cladding tube is smaller than the radius or one half of the width of the core. The core has an attenuation constant for the terahertz waves lower than that of the cladding tube. The waveguide guides terahertz waves mainly inside the core, and has a simple construction.

    摘要： A harmonic generation microscopy employs a laser device that emits a laser beam having a predetermined wavelength that causes no autofluorescence in a biological sample and that, after excited, induces both the second and third harmonic waves. The laser beam is projected onto a sample and an observation beam from the sample is received. The observation beam is directed through a splitter to separate the second harmonic wave and the third harmonic wave both of which are then converted into corresponding electrical signals. The electrical signals are fed to a computer-based image processing equipment to form an image of the sample on the basis of the second and third harmonic waves.

    摘要： The invention discloses a plastic waveguide for guiding terahertz (THz) wave with a wavelength ranging from 30 to 3000 μm. The plastic waveguide includes a core and a cladding layer. At least part of the core is made of a first plastic medium having a first refractive index, and the maximum length of a cross-section of the core is smaller than the wavelength of the guided terahertz wave. The cladding layer surrounds the core and has a second refractive index lower than the first refractive index. In the invention, only one wave mode is propagated in the plastic waveguide, and a first attenuation constant of the core for the guided terahertz wave is higher than a second attenuation constant of the cladding layer for the guided terahertz wave.
