A new infrared laser based alarm |
| abstract |
The subject invention relates to a new alarm which is based on using a quarternary tuneable Mid-IR laser to measure both particles and gas at the same time. The measurement is done within an area of which the gas of interest will absorb the Mid-IR radiation. By widely tuning the emission wavelength of the laser, several wavelengths can be measured in order to accurately find both gas composition and particle density with one laser based sensor. We tested a new device which use radiation between 2.27~m and 2.316~m. Metane gas reduces intensity of the radiation at certain wavelengths in this device, while particles/fog reduce intensity for all wavelengths. In this case, fog should not trigger an alarm, while methane leaks should. This can also be applied for CO and smoke in which one sensor will measure both parameters to sound an alarm instead of just one parameter. |
