Function mlx9064x::calculations::t_ar [−][src]
pub fn t_ar(t_a: f32, t_r: f32, emissivity: f32) -> f32Expand description
Calculate $T_{a - r}$
$$ T_{aK4} = (T_a + 273.15)^4 \newline T_{rK4} = (T_r + 273.15)^4 \newline T_{a - r} = T_{rK4} - \frac{T_{rK4} - T_{aK4}}{\varepsilon} $$
This is the part of the process for calculating $T_o$ (the temperature detected by a pixel)
that compensates for IR radiation that is reflected by the object being measured as
opposed to being emitted by the object. To do this the temperature of the surrounding space
(t_r) as well as the emissivity ($\varepsilon$) of the object are combined with the ambient
temperature of the sensor itself (t_a). This calculation is described in section 11.2.2.9 in
both datasheets.
