Abstract
A method and system for UV detection of sterilant concentration and dissipation in a volume of a chamber may comprise focusing cameras on at least one point of an object in the chamber; transmitting UV light and sterilant into the chamber; scanning, using the cameras, the at least one point of the object and determining an amount of absorbance at the points; calculating, using the amount of absorbance, a concentration of the sterilant for each of the one or more points; and when the concentration is greater than a threshold, removing the sterilant from the volume. The sterilant may be hydrogen peroxide. The cameras may be stereoscopic cameras. The chamber may be partitioned into a grid of voxels for scanning.
