Professor Charles and his team recognised that key to getting the answer was to obtain
optical spectra a number of times during each dip cycle, essentially studying how their colour changed with time.
"Linares and collaborators circumvent this problem by using high-quality
optical spectra from the Gran Telescopio Canarias and other telescopes to identify, for the first time, absorption lines from both the cool side and the hot side of the companion star.
The
optical spectra significantly show the impact of fiber dispersion on the baseband signal recovery.
An optical spectrum analyzer (Ando AQ6317B) and an oscilloscope (Tektronix TDS3054B) combined with a 5 GHz photo-detector (Thorlabs SIR5) are employed to simultaneously monitor the
optical spectra and temporal profile of the output pulse.
The aim of research works, the results of which are presented in this paper, was to determine the application possibilities of optical spectrophotometry for detection of an electric arc and to analyze the measured
optical spectra within the range from 200 to 110 nm by supplying various voltage levels.
Figure 3 shows the EEL
optical spectra, which have two modes corresponding to the polarisations of the device.
His topics include vector analysis and Maxwell's equations, electromagnetic units and electric charges, methods of determining electric field and potential, the classical and quantum theories of lights, the classical and quantum theory of light-matter interaction,
optical spectra of materials, the optics of eyes, electron microscopy in scanning and transmission modes, and fluorescence diffuse optical tomography.
The spectrograph will be capable of obtaining simultaneous
optical spectra of up to 300 faint galaxies or stars at wavelengths between 390 and 1000 nm.
Figure 3 shows the
optical spectra obtained at the input of the PCF, output of the PCF, and after OBPF (corresponding to points A, B, and C, respectively, shown in Figure 1).
The
optical spectra can be largely varied depending on the material and size of the metal nanostructures [1-10].
The scientists came to their conclusions after analyzing hundreds of
optical spectra measured with the SMARTS 1.5-meter telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile, as well as reanalyzing previously published data on the stars.
Some specific topics covered include phonon fluctuations, the spectrum of optical absorption coefficient and optical parameters in GSM, and
optical spectra and morphology of a-Si:H and a-SiC:H films.
