ozone detection by laser

Ozone Laser Lidar - Everise Technology Ltd.

The ozone laser lidar measures the gas concentration by making use of absorption characteristics of the gas to be measured. The lidar system emits two laser beams with similar wavelengths. The gas shows very strong absorption ability to one laser beam, while shows very weak or none absorption ability to the another beam.

Ozone Detector, Trioxygen, O3 gas equipment - GazDetect

Ozone health effects Ozone (O3) taint varies from colorless to blue with a bleach-like pungent smell, detectable from , ozone is a strong oxidizer and can ignite explosions. Although its toxicity depends on several factors (temperature, pressure, concentration), ozone is very harmful for the breathing system (lungs, nose, throat) and can irritate the eyes.

Observation of atmospheric ozone by dial with Raman lasers …

Since the XeCl excimer laser (308 nm) was first used in Differential Absorption Lidar (DIAL) for stratospheric ozone detection, the XeCl ozone lidar became a useful tool for the monitoring of the stratospheric ozone concentration. Shorter wavelength lasers are needed for the observation of ozone in the troposphere where the ozone concentration is about one order of magnitude smaller than in the …

Ozone Detection | Detectors Available at Air-Met Scientific

Ozone Detection; Ozone Detection. Ozone. Ozone (O 3) is a triatomic molecule consisting of three oxygen atoms. It is an allotrope of oxygen that is much less stable than the diatomic O 2. Ground-level ozone is an air pollutant with harmful effects on the respiratory systems of animals. The ozone layer in the upper atmosphere filters potentially damaging ultraviolet light from reaching the Earth's surface. O …

Satellite ozone profiles checked using ground-based laser radars

This ESA-funded project involves 13 LIght Detection and Ranging (LIDAR) stations around the world (see Figure 2) measuring ozone and temperature profiles. DIfferential Absorption Lidar (DIAL) systems emit high-energy (∼200mJ) ultraviolet laser pulses at two different wavelengths (usually around 308 and 353nm). The differential absorption effect of ozone is exploited to derive ozone profiles between 10- …

[PDF] Open-path ozone detection by quantum-cascade laser | …

Ozone spectrum was taken by fast repetitive sweeping of a quantum-cascade laser wavelength over a spectral feature from the ν3 absorption band of ozone, centered at cm-1. Short (100 ns) sweeping times were essential to prevent line-distortions caused by atmospheric turbulence. For fast wavelength sweeping, a technique that employed the thermal chirp during 140 ns excitation pulses was used. The …

Detection of ozone by differential absorption using CO2 laser ...

The differential absorption method with the conventional CO2 laser is discussed for the detection and monitoring of ozone in ambient atmosphere. By using the P(14) line in the (00°1 to 02°0) and the R(16) line in the (00°1 to 10°0) band, the measurement of ozone was made in a field. As an experimental result, the minimum detectable concentration of ppm was obtained with the system, and the …
