Detecting Spectral Lines in Explosions

Click For Summary
SUMMARY

This discussion focuses on detecting spectral lines in high-temperature environments, specifically during explosions. The user is developing a sensitivity model for a short wave IR spectrometer and seeks methods to identify spectral lines amidst the intense luminosity of explosions. The response highlights the use of blackbody radiation principles and optical pyrometry to ascertain temperature, which aids in identifying characteristic emission lines from specific elements.

PREREQUISITES
  • Understanding of short wave IR spectrometry
  • Knowledge of blackbody radiation principles
  • Familiarity with optical pyrometry techniques
  • Basic concepts of spectral line detection
NEXT STEPS
  • Research the principles of blackbody radiation and its applications in spectroscopy
  • Explore advanced techniques in optical pyrometry for temperature measurement
  • Study the characteristics of emission lines from various elements in high-temperature environments
  • Investigate the design and calibration of short wave IR spectrometers
USEFUL FOR

Researchers in spectroscopy, physicists working with high-temperature phenomena, and engineers developing IR detection systems will benefit from this discussion.

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.
 

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
