按照的方法,热象仪性能的综合参数C可由文献[2]中的公式(16)导出。若背景温度为T_φ,目标与背景的温差为△T,则系统的信噪比μ可以表述为
According to the method, the comprehensive parameter C of the thermal imager can be derived from the formula (16) in [2]. If the background temperature is T_φ and the temperature difference between the target and the background is ΔT, the signal-to-noise ratio μ of the system can be expressed as
