Detecting Spectral Lines in Explosions

AI Thread Summary
Detecting spectral lines in explosions, particularly from a powerful blackbody, poses challenges due to the intense heat and luminosity. A sensitivity model for a short wave IR spectrometer can aid in this detection process. Using an optical pyrometer can help determine the temperature of the explosion, which is essential for identifying characteristic emission lines from specific elements. This approach allows for the analysis of spectral lines despite the overwhelming background radiation. Understanding these methods is crucial for accurate spectral analysis in high-energy environments.

Hi All,
I am working on a sensitivity model for a short wave IR spectrometer. And I have come up to a few questions that I had never thought of before and that seem really interesting (and I still don't know the answers, so it'd be great if anyone had any insight!)
Well, I need to look at an explosion (say powerful blackbody) and take an IR spectrum to detect few things. Now, the explosion itself is hot and luminous, so how do i detect the spectral lines I want? In short, how do you detect any spectral lines in such an environment?
Thanks for any help...

Well, one can look at look at a blackbody radiator to look at the temperature (basis of optical pyrometer) and then look at particular (characteristic) emission lines from particular elements, based on the temperature determined from the optical pyrometer.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below.

Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
