An system and method is disclosed for determining a concentration of at least one gas in a container. The system and method includes detecting light reflected by a surface inside or behind the container, or light refracted or scattered by the container, with a detector, wherein the detector provides a first signal related to an intensity of the reflected light, and a second signal related to a position of reflected light being detected. The first and second signals are used for estimating a concentration of the at least one gas inside the container.
