| Abstract: | The multiwavelength pyrometer with prisms for beam split has been used to measure the true temperature of ablative materials burnt by oxyacetylene flame. The effects of stripping, steam and smog should be reduced to a minimum level by meticulous choice of effective wavelength and signal processing method. The high temperature scale calibration has also been solved using"One Point calibration". |
