Abstract: (1002 Views)
In this paper, due to the importance of simulating gas optical sensors in the construction of these sensors, two non-dispersive infrared and visible-ultraviolet sensors have been simulated, which are used to detect NO and NO2 gases, respectively. Because NO2 gas overlaps with water vapor in the infrared region, the sensor has been examined in the visible-ultraviolet region. After simulation, the information obtained from the simulation is investigated and the effect of cell length in the case of a simple reflection tube cell on the number of rays reaching the detector, the length of the optical path and the angle of light on the surface of the detector interference filters is investigated.
