摘　　要：利用热释电管红外热电视在成像的同时直接测量温度的技术,正在不断完善中.本文指出在平移模式工作时低空间频率、恒定平移速度条件下系境输出电压对靶吸收的红外辐射功率成线性关系;从理论和实验得出了测温公式(5/4次方公式);最后讨论了影响测温精度的诸因素。Temperature measurement of infrared thermal television using the pyroelectric vidicon (PEV)is being perfected. It is presented in the paper that the output voltage of the system is linear with the infrared radiant energy absorbed by the target of PEV in panning mode on condition that the spatial frequency is low and the panning velocity is constant. To proceed from theory and experiment, the temperature measurement formula is deduced. Several factors influencing precision on temperature measurement are discussed.
