Sensitivity Model for a detector

Click For Summary
SUMMARY

The discussion focuses on creating a sensitivity model for a near-infrared detector, specifically for detecting hydrogen (H2) spectral lines during an explosion. The user has conducted radiometric calculations to account for noise factors such as dark current and sky background, determining the minimum signal intensity required. The main challenge lies in isolating the H2 lines from the explosion's background noise. Effective strategies for achieving this isolation are sought.

PREREQUISITES
  • Understanding of radiometric calculations
  • Familiarity with near-infrared detection techniques
  • Knowledge of spectral line detection methods
  • Experience with noise reduction strategies in optical measurements
NEXT STEPS
  • Research methods for isolating spectral lines in high-noise environments
  • Learn about advanced filtering techniques for near-infrared signals
  • Investigate the use of spectroscopy in explosive environments
  • Explore software tools for simulating radiometric detection scenarios
USEFUL FOR

This discussion is beneficial for optical engineers, researchers in spectroscopy, and professionals working with near-infrared detection systems, particularly in high-noise applications such as explosive environments.

hello,
I have to make a sensitivity model for a near infra red detector and I need help. I have so far done radiometric calculations taking into account noise, due to dark current, sky background, etc and calculated the minimum signal intensity i need. However, i have a few blocks:
I need to determine how strong my spectral line needs to be given that i am actually trying to detect it in an explosion (similar to detectng H2 lines in an explosion using near IR?) How do you not see the explosion and just see your H2 lines?
thanks
