Making proper measurements when looking from one atmospherre into another

Making proper measurements when looking from one atmospherre into another
Hello everyone,


I am running into a problem. I am trying to make measurements of objects (and later children) inside an incubator in which the temperature is higher than the temperature in which the camera will be. The material of the incubator has a very high emissivity in the wavelength range I will be performing my measurements (7-14um), and is thus not suitable to measure through.
On this object (a cardboard box) I have placed a temperature sensor (a thermistor) without coverage.

This creates the situation as seen in     .

In this situation, two atmospheres exist who are also in contact with each other, and will combine at the opening of the incubator. I do not know how this happens, as I lack thermodynamics knowledge.

In an attempt to make this situation less complex, I have found material through which the camera is able to measure radiation, which would create the situation as seen in     .

Essentially this creates two separated atmospheres.

Now, the problem I have, is that I am not quite sure how to adjust certain parameters, i.e. reflected apparant temperature, atmospheric temperature, etc. for either situation. Using a plethora of different settings, I can not synchronize the camera measurement with the temperature measurement, which is ultimately my goal: make accurate thermographic measurements of the object/child in the incubator.

Would any of you know where I can find any literature on this, or how to solve this problem? I am using a FLIR SC305 using FLIR Quickplot (I sadly no longer have access to IRResearchMax).

With kind regards,
