[Investigations of transient time-dependent spectral multi-channel measurement for shocked KCl crystal].

In this paper, the authors reported a new method for measuring transient time-dependent spectra using multi-fiber delay coupler and optical multi-channel analysis technique. The fiber delay coupler consists of five fibers with different lengths and its time-delay between two fibers is determined by the different fiber lengths. The light beams that came from the fiber coupler were coupled by a lens system into the slit of a spectrograph and formed a spectral pattern on the focus plane of the spectrometer.

[Simultaneous and real-time collection by multi-fiber coupling and optical multi-channel analyzer].

A new kind of instrument and method for simultaneous and real-time collection of multi-object spectra by using multi-fiber coupling and Optical Multi-channel Analysis (OMA) was reported. The spectral signals of one object, three objects and five objects were collected successfully in experiments. The spatial resolution of 0.

[Investigation of multi-channel collecting and temperature calculating by using minimum error principle for thermal radiation spectra].

A new kind of method of multi-channel acquisition of thermal radiation spectra and temperature calculating was reported in this paper. Employing a tungsten lamp as thermal source, using an optical multi-channel analyzer(OMA) to collect the radiation spectra, the measured temperatures were calculated by using optimum simulation between the measured spectra and Planck black body radiation curves at the determine temperatures according to the minimum errors principle. The results are agreement with standard values, and the errors are near 1%.
