【摘要】 利用遥感傅里叶变换红外发射光谱 ,对红外辐射源的绝对光谱能量分布和热气体浓度进行测量时 ,首先必须对测得的红外辐射源的发射光谱强度进行校正 ,为此 ,需用已知温度的标准绝对黑体对系统进行校正。本文考察了黑体温度对EQUINOX5 5型遥感傅里叶变换红外光谱的响应函数的影响。结果表明 ,仪器响应函数随着温度的升高而增加 ,但当温度比较高时 ,仪器响应函数曲线变化趋小。更多还原

【Abstract】 In order to obtain the infrared spectral radiance distribution of the emission spectrum or the concentration of the gases,the calibration of FTIR emission system is necessary for obtaining an instrument response function of the system.This paper gives the effect of the temperature of the standard blackbody for calibration of EQUINOX55 remote sensing FTIR emission system on the instrument response function.The result illustrates that the values of the instrument response functions increase as the blackbody temperature increased,and tends to a limit.更多还原
