Resonance dip shifts gradually to longer wavelength as the thickness of Ta2O5 film becomes thicker. For the range of liquid refractive index from 1.333 to 1.388,the measuring sensitivity of optical fiber SPR probe coated Ta2O5 film can up to 2235 nm/RIU(Refractive Index Unit).
当液体折射率n0处于1.333~1.388之间时,蒸镀有Ta2O5薄膜的光纤表面等离子体波传感器波长灵敏度达到2235 nm/RIU(Refractive Index Unit);
To realize the measurements,a scanning narrow-band light is injected into EFPI or FBG,the reflected wavelength of FBG and the spectra of EFPI are calculated.

Their fluorescence properties were studied by photoluminescence, which indicated that the luminescence wavelength of 5-and 2-substitued-8-hydroxyquinoline derivatives shifted to red in comparison with that of 8-hydroxyquinoline.
For the finite-difference time domain (FDTD) method, the electromagnetic scattering problem, which requires the characteristic structure size to be much smaller than the wavelength of the exciting source, is still a challenge.
The absolute value of mv is determined by the microscale component of the vortex microstructure, which is commensurable with the sounding sonic wave length.
The wave length of the f-f transition in the electronic absorption spectra of crystalline complex I and Np(V) in a saturated carbamide solution is virtually the same and is equal to 991 nm.
In the long-wave length limit, the velocity of acoustic phonons is isotropic; however, the phonon-phason coupling causes anisotropy of the velocity and of the attenuation of acoustic waves with small wave vectors.
The reflectivity of these coatings is determined as a function of the film thickness (in units of the radiation wave length), optical constants, and the radiation incidence angle.
1. An X-band E. S. R. spectrometer has been constructed. Its sensitivity is such that 3×10~(-8) mole of DPPH can be detected by oscilloscope with S/N=15/1. The five byperfine structure lines of 5×10~(-4) M/1 DPPH benzene solution have been resolved.
The photosensitive field effect transistor is made of a n-channel junction field effect transistor. It has not only the merits of the silicon photo-cell, but also the high input impedance and low noise field effect transisitor as compared to the other photo elements. Its main advantages are high senitivity and relatively quick response in the spectral range from UV to near IR, wide linear dynamic range, useful at 10~(-3)～10~4 lux, low output impedance, direct use in determining absorbance without log ampli...
The IF and LF Laser vibration measurement instrument type GDZ-2 is used to measure the amplitude of a standard vibration table through interferometer and electronic technique. The wave length of a He-Ne laser is adopted to be the standard length for measuring. Then velocity and acceleration of the vibration table can be calculated by the amplitude and frequency measured. With the help of a special computer displacement, velocity and acceleration transducer may be calibrated. In order to attain the given pre...
