Integrated Path Spectroscopy
How the Intensity Modulated Continuous Wave (IMCW) Method works
Advantages of this approach versus other methods:
- Leverages all fiber telecom based components
- Simultaneous transmission of both on and offline wavelengths causes several common mode noises to cancel in the ratio
- Relatively immune to background radiation and scintillation
How 2-D Measurement works
Advantages of this approach versus other methods:
- Provides spatial information about the gas concentrations in the field of regard
- Maps can be used with other ancillary data to provide emissions estimates
- Sensitivities relevant to environmental monitoring with dynamic range and spatial information needed for safety applications
