  • Some Points Regarding a Recent Presentation at ICCF20 on the ‘Lugano Report’ (Rainer Rander)

    Quote from Paradigmnoia

    The temperature can be calculated without ever knowing the total power output.


    For being precise the camera is nit sensitive to temperature but to radiated energy. For making a measurement you must know the ratio of the total emitted power from the body surface and that that would be emitted by a Black Body. So all your reasoning means that total emissivity is an important factor to know during a measure.
    Total emissivity and not band emissivity because, as you demonstrated, that for many bodies the energy emitted in a certain band could be identical.

    Indeed the temperature of an object would be hotter being limited to IR output in a limited spectral band portion of the IR band than it would be if it were a blackbody at the same level integrated radiant power.


    So you agree perfectly with RB0 !
    In fact an object with a limited bandwith emissivity will be really hotter then a Black Body ! This is a real effect and not apperent !
    We should note that in the last postings RB0 is just writing about Quantum Mechanics and Physics and DO NOT consider any detector.
    So her conclusions are valid for all the detectors ! Even thermocouples.


    Quote from Paradigmnoia

    Total radiant power is irrelevant to detecting temperature based on a selected IR window.


    Excuse me sir, in your post you say one thing and demonstrate the opposite. By showing that the two curve are almost identical in a limited region you demonstrate that for obtaining a good measure we must consider all the spectrum !


    Seems that you say one thing but you think your are saying the opposite !

    Quote from Wyttenbach

    if you measure it in total emissivity mode



    What a nice disinformation ! There is NO total emissivity mode in any (common) camera ! Any camera has a sensitivity window that is not constant pixel by pixel and not flat function!
    Using the band emissivity would be a nonsense not knowing the exact sensitivity function for each pixel and for the mounted lens.
    The only emissivity to use is the total normal emissivity, with the proper factory calibration.
    We have pointed out already almost TWO YEARS ago all that! Our post was appeared in ECW and in the 22passi blog.

    Is quite clear that there is an organization devoted to methodical disinformation.
