In my experimental setup I have a purpose built small aluminium tube that has a black layer on the inside to mimic a blackbody.
The tube is heated so the inside emits as a blackbody. A separate temperature sensor attached to the tube gives the temperature of the tube.
I have a thermopile sensor inside the tube that reads temperature of the surface of the blackbody. I am confused how I can convert this data into quantities such as spectral radiance, radiance, wavelengths or flux.
Using Wien Displacement Law I know I can get the peak wavelength emission of the blackbody from
Peak wavelength = wien Displacement constant / temperature
The temperature will be the value recorded by the thermopile sensor.
I really don't understand how to extract anymore data from my temperature reading ... Radiometry is somewhat confusing! Please can someone assist
