A coherent electromagnetic pulse in the range between the far - infrared and microwave region is used as a detection source. the amplitude of the wave is recorded by electro - optical or photoconductive sampling. after fast fourier transform, the amplitude and phase of the wave is given, then the complex refractive index standing for the absorption and dispersion of the material in thz region is extracted
Thz ( 10 ~ ( 12 ) hz )時域光譜技術是20世紀90年代發展起來的一種新型的光譜測量技術,它使用頻率介於遠紅外和微波之間的相干電磁輻射脈沖作為探測源,利用電光取樣或光電導取樣的方法直接記錄thz輻射電場的振幅時間波形,通過傅立葉變換得到測量信號振幅和相位的光譜分佈,進而獲得材料在thz波段的復介電常數,即色散及吸收等信息。In the study, sd2000 spectrometer is applied to obtain radiation spectrum of flame within wavelength 480 - lloonm, from which flame temperature and monochromatic emissivity are derived by newton raphson non - linear method and levenberg - marquart modeling method. the flame monochromatic emissivity is translated in form of f ( / l ) and a ( a ) respectively
在該方法中,採用sd2000型光纖光譜儀測量火焰在可見光( 480 - 1100nm )波長范圍內的火焰的輻射光譜,結合newton - raphson非線性迭代演算法和levenberg - marquardt最優化演算法,得到火焰溫度和單色輻射率變化規律。
