火焰辐射温度场测量系统黑体炉标定

Black Radiation Calibrating Experiment for Temperature Field Measuring System of the Combustion Flame

使用彩色ＣＣＤ系统测量火焰温度场，首先要建立火焰辐射能与ＣＣＤ光信号之间关系和火焰辐射能与温度之间的关系。本文通对光辐射辐度学的研究，给出火焰辐射能和光信号的关系式，并通过人工黑体炉实验，标定辐射能和光信号的关系。

Temperature measurement of the combustion flame using CCD camera is depend on two relationship, one is the relation of the flame radiated energy to flame temperature, another is the flame radiated energy to CCD camera optical signal. In this paper, the latter relationship is set up based on optical radiation theorem, and then the CCD camera system is calibrated by black-body furnace to gain the suitable CCD camera optical signal of flame radiated energy.
