Long optical path length and strong ozone absorption wavelength are generally applied for high sensitivity ozone concentration measurement in ultraviolet absorption spectroscopy. However, high sensitivity of measurement cannot be achieved when the sensor approaches saturation. Here, we derive two eq...
